THE Hollow Handle Knife Thread

I'm going to have Newt make a Caiman for my daughter as a commissioning present with her name and rank etched on it.

I always liked the Explorer it was a well made knife and well designed sheath too.
 
Great stuff! I always found the caiman's attractive, but the recurved edge is very peculiar-looking: It seems to me it would require a rod sharpener...

I just got my sharpened Apparo from Razoredgeknives: Unbelievably, considering where it started from, it is now the sharpest knife I have ever seen or handled... To give you an idea, it similar, or sharper, on the false edge than any knife I have ever owned, and the main edge is much sharper! The edge is perfectly centered top and bottom, which I know is hard to do... It has become my favourite knife. The sharpening was worth every penny of the large expense that it was ($80): The knife needed to be completely re-ground from scratch, essentially...

There was only one downside: I had asked specifically for the sharpeness to remain the same all the way to the point, so the point was initially a little on the fragile side: On the good side, it was not a meeting of two flat lines (looking down from above), but rather a meeting of two curves, so that actually gave it more rigidity than it appeared at first glance: This point issue I consider solved anyway, as I just barely rounded off the point, and it is now much stronger, very unlikely to ever break, in part because of the tall point profile of the Apparo.

The funny thing is this is such an overbuilt-feeling knife, the sharpness it displays creates a strange contrast: Like hammer that can separate floating silk... It is the kind of sharpness stories are written about...

I used to object to its length being only a 7" blade with such a large handle: I think now this makes it more confortable to carry in my usual right front inside-the-pants manner. Anything over 7.5", maybe 8" at most, is really just too much for this kind of carry, I realize now...

The leather sheath I got from Savage was superb in execution (just a standard sheath, not designed for inside the pant carry), particularly the stitching, rich leather color, thickness and quality, but I thought the snap felt of a lower quality and was weak in releasing: Very quiet when you unsnap is not necessarily good... Then I realized that the leather was of such superior quality (perfectly designed to accomodate the overly wide guard of these types of hollow handles), that the knife held perfectly with no snaps. (In fact the first Rambo knife was also carried in a snapless sheath): I then removed the snap, covered the remaining post with a nice large pant-catching button, and any feeling of lower quality of this sheath disappeared.

I have only blade photos, as my camera's battery just ran out:

I can recommend getting your knife to Razordegeknives without any reservation. The Savage sheath is excellent, but could use stronger snaps...

The large sized handle of the Apparo is very confortable and allows more content, but the inner compartment is much shorter than the Reeves. Despite the shortness, I found the extra diameter significantly more capacious...

One word of caution: The blade finish looks a bit smoother in person than in the photos, and the advantage I found of this kind of "cross-hatched" satin finish is that by sanding vertically repeatedly with worn 350 grit sandpaper, you can easily remove any accidental scratch to invisibility, without your sandpaper strokes showing at all, even when moving the blade around under a strong light... More pics later:

Again, Razoredgeknives is well worth the money...

That said, after getting the chance to check out a couple of the more modern hollow handled knives, I am taking a trip back in time revisiting one I had for a short time back in the 80s. It was in my opinion a much under rated knife, thanks mostly to the Exlorer Knife Co. out of Asia, that was known for producing a lot of fragile junk. The Explorer Survival Knife (later called The Explora to separate it from the other company), made by Marto in Toledo Spain was better made than any of the hollow handles I have seen come out of Asia, and many from elsewhere. This one is right at 40 years old, and hasn't exactly been sitting around in a safe.

I know I have one of those somewhere, but the Explora version with a curved blade. I need to go digging through my garage for it...
 
I finally got around to photographing my entire survival knife collection: There's not much, but I have only really restarted my interest in knives this year, the Jereboam bought in 2009 being an oddball purchase at the time. For 12 years previous to that, all I really had was a Spyderco Civilian!

What do I consider a survival knife?: At minimum a knife that has a provision to light a fire! I think a knife that carries small items is pretty much what distinguishes a survival knife: This means it does not necessarily have to be a hollow handle, as fire making can be carried in the sheath. However, an oddball requirement of mine is that the knife has to be carried inside the pants (I find concealment, protection from cold, weather and loss not to be options), and that makes the sheath carry of items troublesome: This is why the hollow handle wins in my mind! Another thing the hollow handle does better than anything else in my opinion is carry pills: No other container does this better actually, because pills are fragile, and larger containers make a lot of noises with them... I don't need pills for my health, but painkillers to help sleep are often an overlooked item...

So far my attempts to find the best survival knife has led to a lot different shapes and sizes: I'm still trying to sort out which I like best, bearing in mind that what I like and what works best are two very different things:

DSC01601_zps8440d827.jpg


DSC01618_zps2ff17354.jpg


Note the Randall sheath is not modified to improve inside the pant carry, but does OK as is (survival items are in the pouch, in a very strong plastic box, but not waterproofed). The Reeves sheath is mostly unmodified as well, and is much more suited to inside the pants carry, thus the sharpener was added on the side and not the front for this reason (despite appearances, the sharpener mounting is fully rigid and all but indestructible)

Out of the box, the Boker Apparo was the most incredibly dull-edged knife I have ever seen, and was immediately sent to "Razoredgeknives" with the instruction to make a new blade out of this blank stock: The result was amazing, but cost me about 3/4 the price of the knife... It would be very unpleasant to send out a very expensive knife like this, but I have confidence in that company now...

The Randall was brand-new, and sharper, but the next dullest (it could barely slice paper, and not cleanly), and most of all it had the most incredibly dull point I have ever seen on any knife, even far worse than the Apparo: A rounded-tip monstrosity that would not even do cosmetic scratches on a leather jacket (not to mention anything beyond it!)... I couldn't take sending that one in, so I did the work myself: The Randall edge is extremely thin (0.5 mm), and so responds very well to sharpening: The point was quite another matter, but I got that one done without too much cosmetic damage: It took more than a little skill and effort to keep the huge point grinds level and nice-looking, and this kind of work is definitely not for everybody... As is, the knife could not be used at all... I'm sure this is common in Randalls, because the point looked the same as that of all the others.

The TOPS Hellion was barely useable out of the box, but at 25° per side extremely inefficient at slicing, and, even for chopping, squandered all the weight advantage you carry at your own effort: It did tolerate being taken down to 12-13° per side, although the grind is now very deep (as visible), and almost level with the metal above it(!): The 5160 steel is the easiest steel to sharpen I have ever seen, and has none of the edge-rolling tendencies that cause me so much trouble with 440C (the forged 440B Randall behaves much better than regular stock-removal 440C for some reason, with far less rolling than the Apparo, despite similarly thin edges now: I think this could be due to the forging process). The main Hellion edge was done with a flat stone, but the tanto bevel point required a power tool I made with a drill: A first for me, as doing the point by hand would have been far too time consuming...

To be continued...

The Chris Reeves Jereboam Mk II was the only acceptably sharp knife out of the four, and still has its original edge despite a little bit of use: Its A-2 steel however is widely reported by several sources to hold its edge very poorly, with some edge flattening after a few hundred chops on soft wood, which really is unacceptable: This is why I adapted the sharpener to it as a makeshift solution... I have to sort out how true this poor performance is later...

In order of sharpness now: Apparo (by far): 0.34 mm edge base, Randall: 0.5 mm edge base, TOPS Hellion: 1.87 mm edge base, CR Jereboam: 1.0 mm edge base. The Hellion would desperately need a hollow grind, as I worry the thick edge base means the superb edge it now has will get worse fast with every re-sharpening: Hollow grinds are much superior on thicker-based edges, because they allow you to back into the blade when sharpening...

The Apparo has a Savage-made sheath that turned out very well, but the snaps were weak so I removed them: The leather is so thick, and the huge guard so wedged in it, that it completely tolerates snapless carry (as did the original First Blood knife). I removed the sharpening stone pocket as I felt 440C made sharpening less important: It sharpens poorly but holds an edge extremely well (it is generally much underrated in that regard).

The Hellion had its sheath shortened, and the pocket covers removed (unimportant, as they have an elastic that pinches their openings): I cut off the excess blade insert length, and wrapped the remaining nylon towards the back. It actually rides better than the Reeves now, as the sheath is softer. The two pockets are a huge help, as they allow separating fragile items from tough ones, and this allows keeping them away from the belt pressure point: With the constraints of inside the pant carry, the sheath can still carry a 4" flat diamond sharpener on top of what the capacious Apparo's handle can carry, but only four pills in a plastic bag versus 8 more securely in the handle... The Reeves handle is much longer inside, but still noticeably less capacious than the Apparo...

The Reeves Jereboam is the closest thing to a survival knife I would have designed: Ergonomically, especially including the sheath, there is not one item I would do differently (except for the steel's edge-holding properties!). The Hellion I think would be the most capable, but wastes weight with a full tang, and should have been hollow ground with a thinner edge: I think for survival it is otherwise the best design, because I found the Jereboam really marginal as a chopper, despite a very thick heavy blade, with a thin hollow grind, that boosts its pathetic 1/4 inch balance point to an identical chopping performance to a BK-9!

The Apparo is probably the most versatile knife of the four: Most confortable to carry, and the most features: The thin edge does boost its chopping abilities, but chopping is still a weakness, as its balance point is just behind the guard... I resharpened the thin "Razoredgeknives" edge after some light use, and found 440C, as always, rolls and makes sharpening difficult. I still managed to improve slightly on an amazing edge... I did not use it enough to comment on edge holding, but I think it should be good.

The Randall is a $600 knife in the sheath and handle, but feels like a dime store item in the blade... I attribute some of the uneven blade surfaces to the forging process, which sort of makes it acceptable I suppose... The blade was straight and the grinds even, so at least the basics were there, but the feeling of precision grinds you get in a cheap Seki japan blade is matched by less than 70-80% here... Even the TOPS Hellion felt somewhat more rigorous in its blade grinds, though be warned it hides for some reason a heavily pitted surfaces under that paint... Don't strip it!...

The Randall is advertized as 1/4" stock, and the tang is, but the blade is much thinner: Tang: 6 mm, base of blade: 5.69 mm, flat at start of saw: 5.17 mm, flat at the tip of saw: 4.45 mm: This robs this blade of much needed mass, and the result is a balance point that is at the guard (because of this blade-light feel, don't expect your knife to feel "expensive" when you first hold it)... I really hope this is intentional, or again due to forging, and not me paying $600 for some newbie's training knife... All Randalls are different, and while this is supposed to be "uniqueness", to me it seems more like loose tolerances: I had picked this knife on Ebay because it did look different from all the other similar Model 18 blades I had seen. The blade comes in at 7.4 inches, not 7.5, but it does fill the sheath exactly, so I suppose that is ok... That no-point point was not funny however...

For all its flaws, the Randall has an edge nearly as thin as the "re-built" Apparo, and this edge proved easier to work with despite much heavier work done on it by me, when compared to my work on the Apparo (due to the Randall's ease of edge-taking with no edge rolling): I attribute this to either the heat-treat or the forging, since they have nearly the exact same steel to start with... Whatever the case may be, this combination makes it the best edge, and thus in theory my best knife...

I should have gone for a Model 18, especially given this thread(!), but what I saw of a broken Model 18's tang, barely 3/4" with no hole, or any kind of locking feature, did not inspire confidence (neither did the silver soldering)... I did not even know the 14 could have an 18 blade, so when I saw it I decided to use the stone pouch for storage instead: The correct-size plastic box was cut out from a larger one (holding various hardware fixtures in separate compartments)...

I'll go in greater detail later on what I put in each knife. I do plan to test/use some of them, but I loathe to use edges I worked on: Edges I paid, no problem! :)

Gaston,

Nice collection and good writeup. I enjoyed it. Tell me about inside the pants carry. How does that work? It sounds uncomfortable and awkward, especially with large knives.

No need to worry about the #18. For 50 years, it has had an excellent track record of military and civilian use. Here are a couple of posts that I saved from another forum on how the #18s are constructed.

"On #18’s, we use 1100 degree silver solder for the 172,000 psi necessary for strength of attaching the hilts and handles." - Gary Randall

"The blade is soldered at both sides of the hilt and then the handle is soldered to the hilt. In 30 years, I’ve seen only one #18 returned with the handle apart from the hilt and it was heavily abused." - Scott Maynard, Randall Shop Foreman
 
Gaston, great post. I agree with most all of what you said, but I would like to add a few things from my personal experience that you may find interesting.
In no particular order:

1.) I agree with you on 440C and edge holding. PROPERLY heat treated and ground 440C will perform very well, and according to some tests, is not that far off from some of today's best steels. Largely, and this is my opinion but based on experience and actual use, people's perception that 440C is not a great steel comes from knives that weren't given optimal heat treat, and/or ground thinly enough. I have no doubt that plenty of people have used a 440C blade that failed to meet expectations. Often mediocre heat treat and the edge geometry of a brick are responsible for this, though. Cryogenic tempering appears to be particularly beneficial to this steel.

2.) I have a Reeve hollow handle knife, the one pictured in the original post of this thread on Page 1. I have used it quite a bit, both chopping and slicing/carving wood. I have experienced excellent results with edge retention on the A2 steel. Somewhere I think you mentioned the sharpness of the edge, as far as cleanly slicing paper and such. This is the process I currently use on the outdoors/survival knives that I sharpen for customers. I sharpen the edge on 180 grit abrasive, then polish the edge on paper wheels. I do it this way and I have a sharp, toothy edge. It will roughly shave hair, or roughly slice paper, but cuts better in wood/cordage and things you actually encounter in the woods, where these knives are designed to be used.

I used to sharpen them on waterstones, going to either 8,000 or 10,000 grit finish. The knives were unbelievably sharp at this point, and would take hair off your arm like a razor, you wouldn't even feel it. But on more than one occasion I went to cut cordage, such as sisal rope, and the blade slid on the rope without cutting. I had to put much additional force to get it to bite and cut. But the toothier edge I put on this way bites better, and I find maintains that edge longer than a very finely polished edge. After all, I don't shave or cut much copy paper in the woods. I have found a similar edge can be attained by using the red fine DMT diamond stone, works great. Just my experience, take it for what you will.

3.) As far as the strength of the Randall soldering method, first, I have seen a pic somewhere, I will have to look for it, of the handle broken clean off of an 18. Every company and maker has a dud once in a while. To my knowledge, that is the only one I have actually SEEN or heard of that was verified. Given the number made, that is pretty impressive. The high temperature silver solder they use is similar in strength to a MIG weld. Given the way the handle broke off, the soldering was not done properly, or the metal was not cleaned/fluxed properly, in my opinion. Again, everyone has duds. There are pics of broken BK9's, Busse's and pretty much everyone else as well.

I believe they do add epoxy now, although it is my understanding that the epoxy's only official function is to prevent items from getting stuck around the tang in the handle. I will add that I have tested handle tubes that have been silver soldered to guards in my shop, and I have been unable to separate the two using hammer blows. It is important to differentiate silver bearing solder (soft solder), such as is typically used around a blade in a guard, and hard solder (silver brazing.) Silver brazing is VERY strong. It is what I referred to that withstood a solid minute or so of beating with a hammer, and is what Randall uses on their knives.

Hope you find that info useful, and nice post.

I'm going to have Newt make a Caiman for my daughter as a commissioning present with her name and rank etched on it.

I always liked the Explorer it was a well made knife and well designed sheath too.

I think that will make a hell of a present Dave! I wish Newt would get on about doing the smaller ones he and I have talked about, but I know moving the shop put him behind on orders. I know some do not like the re-curve but he also makes it with a straight blade which is sweet too.


I know I have one of those somewhere, but the Explora version with a curved blade. I need to go digging through my garage for it...

The first one I had was the later Explora, when they were trying hard to differentiate themselves from the horrible Explorer Knife company. These knives are very well made for what they are. I am in the middle of a deal for an older one from the first run, still in like new condition. For my explorations and photography hikes in the subtropics where I want to travel light it gives me a lot of capability in a small package. If you look through this thread, you'll see my favorite use for the wire cutter :)

In no particular order....

I have yet to try the Randall 18, though I hope to, and I never did put my one CRK hollow handle through any real hard use or abuse, but I agree with you 100% on the 440C. Properly heat treated and cryo-quenched 440C does very well, and is a really good knife steel. But I went through several crappy ones before I got a good one and learned what it was really supposed to be like.

No need to worry about the #18. For 50 years, it has had an excellent track record of military and civilian use. Here are a couple of posts that I saved from another forum on how the #18s are constructed.

Well, here is the post in Bushcraft USA thread ("Post your hollow handle survival knife" post #495, another big thread...) that kind of got me scared of the Model 18, although it did happen to an old one (incidently, note how pointier in profile the older style blade is, which looks a bit blander to my eyes):

: " Quote:"I don't think you can break an 18 at the handle joint unless you're trying."

-------------------------------------------------------------------------------------
Ok, I'm in lol. Thirty years ago I was showing off with a Randall knife that I had traded for a Gerber MK1 and twenty bucks cash. Knocking the edges off a 4x4 that was going to be inserted into a pipe for a clothes line pole. The 4x4 would give purchase to the wood screw hook for the line. I didn't think I was trying to break it , nevertheless it took a sideways bend as 3/4 of the silver solder holding the handle on separated. I had a friend who professed to be a knifemaker try and solder it back together. He looked like he was in over his head, started to grumble about not having enough heat when he couldn't get the solder to stick/ flow. I decided to quit before he ruined the knife, never got back to fixing or having it fixed. I was surprised at how little was holding the handle on. haven't had a need for the knife, didn't have a big investment so this is how it rests for the last thirty years.

There are several things to note: Someone posted online, on Knifeforums, a description of the Model 18 assembly process that is just pure fantasy, claiming, among other things, that the stub tang is a full 2": Even if it is longer on newer models, the compartment length tells us the tang cannot be more than 1.5 inches on new models: To quote my own reply: "More recent Model 18 handles are currently made of 4 1/4" of exposed tubing (probably still with barely any indentation into the guard), allowing, on current production, for a depth of compartment of just under 3" from the mouth of the opening: This means that the tang cannot possibly be more than 1 1/2" long in those very recent vintage knives, including the portion going through the 1/4" guard thickness."

On the photos above, the tang looks like it is barely 3/4", but the knife is well over 30-40 years old, so around 1 inch to 1.5 inches is still possible... I don't know why Randall is not out in the open about this...

Then there is the additional compromise (in my view) that here the guard is an essential component of the whole assembly: Yet it is brass, which is much softer and less rigid than steel: There is no getting around the fact that to use brass for such a purpose, in such a crucial role, is less than optimum...

Also, silver soldering is supposed to be strong, and I accept that for compression forces, but for optimal strength I think any correctly designed hollow handle tang should, in addition to soldering, provide a mechanical "lock" to the soldering (or preferrably directly from the tang to the tube of the handle itself), in case the adhesion surface of the soldering is ruptured by the vibrations from chopping: The fact that the exposed tang shown above is devoid of slots, holes or projections to "grab" a material, whatever it may be, just seems like bad design practice (it does seem from what Sam Wilson says that silver soldering comes in several very different types, and that some may be very strong)... You can be sure the Martin-designed Apparo has some sort of mechanical locking of its tang, and because of this I consider it no different than a Chris Reeves in integrity (it probably is even stouter in fact, given the A-2's apparent brittleness).

This is not to say that the Model 18 is a poor knife; it could still be very strong, but getting one does ask you to part with over $500, and the concept of the attachment certainly would need some extensive litterature to reassure prospective owners... I'll probably get one just to beat the daylights out of it before I make up my mind about it...

I also wish it came with the handle wrapped, because getting tension and neatness on wrapping is a bit of a job: At $130, the wrapping on the Boker Apparo is superbly tight and very high quality: Identical or better than the actual Martin SURV9 custom which I had! Surely Randall can spare some wrapping effort...

As for inside the pant carry, it is very confortable to me, right side kidney hollow, and the only issue I ever encountered is with biking with over 8" blades, because the motion from pedaling does squeeze the longer sheath uncorfortably: No issues from 8" blades down. It does require the person to be on the slim side... Even the 9" Hellion is reasonably confortable biking since I shortened the sheath, but note I am 6' 3". The Apparo is virtually unnoticeable, despite its humongous guard, which to my surprise causes no carry issues at all, and greatly helps securing the knife inside the sheath without the snap...

An important point with inside the pant carry is the leather sheath should be very thick and rigid, or it will "twist" slightly, which over time causes blade rubbing on the sheath, which can cause slight cosmetic damage, or even some slight edge dulling in its "belly" in the worst cases: The Reeves sheath is just rigid enough to avoid that, but because of its length it does twist just a little, causing one slight rubbing spot on the primary grind line... The Randall and Apparo sheaths are really much more rigid, in part because they are shorter, and so don't suffer the higher twisting forces of longer sheaths... This is why 7-8" is really the limit. The Hellion has a insert that doesn't really twist like leather does, because the outside nylon is a bit loose to it...

Inside the pant carry has many obvious advantages to my eyes, especially with uncovered metal handles which can get very cold, and even more important is avoiding losing the knife without noticing (as I hear numerous times from servicemen who don't have the choice to carry "inside"), or getting water or dirt inside the sheath... It is also probably easier to pull the knife out of a sheath that is correctly tight, compared to belt carry, unless the belt sheath has the awkward leg tie to hold it steady as you draw (I'm guessing here, as I've never carried a knife that way)... I also don't like the idea of displaying knives, large or small, anywhere. If not biking, even the Reeves Jereboam or Hellion are perfectly confortable walking, and even running, and this holds true for prolonged sitting. The only limitation I can think of is biking or crouching down for long periods, which might require something under 7-8"...

Another requirement is a solid one piece leather belt, not the stiched together kind of belt, as the belt's tension is what makes the carry confortable... The pants don't contribute anything, so any pants will do. A stub or projection on the upper part of the sheath does help stabilize the sheath, but is not an absolute requirement. Extra thickness of the upper middle of the sheath seems to help hold the knife, but stone pouches are usually a bit too much and too short...

Still having a hard time visualizing "inside the pants' carry with a large knife. I'd ask for photos, but that just doesn't seem right. :D

BTW, whatever Sam Wilson says, you can take it to the bank. :thumbup:

Gaston,

I am definitely not a Randall historian by any means, but I seem to recall that they used to make the tangs longer at some point. They kept shortening them until they settled on around an inch or so, for length inside the tube. Again, I can't be certain about that, but that's what I seem to recall.

Regarding the rest, as far as making it stronger and different methods of construction, I have to agree with you. I think there are stronger ways of doing it. But I also think this method is very strong, as well. This is the ONLY one I have ever seen fail. That's pretty impressive, as I'm sure thousands of these have been made. Again, I haven't examined the knife closely, and I'm no expert, but it looks like the soldering job wasn't done properly, either due to prep or fluxing issues.

I also agree that adding a mechanical fastener is better. But I think it's important to remember that this is a combat knife, and to my knowledge, never designed to be batonned or beaten on. Even so, many have been, with this being the only failure that I am familiar with. As to the brass, the solder used will wet out and adhere quite well to brass as well as stainless, so that shouldn't be a problem. The flexibility of brass shouldn't be a big deal, in my mind anyway. I believe that guard is about 1/4" thick. I don't know what someone will be doing that can flex a 1/4" thick, 3" long piece of brass soldered to steel, but it's nothing the knife was intended for.

The solder that is typically used on guards around the ricasso of the blade melts at 430 degrees, and is designed primarily to prevent water/blood/whatever from getting down inside the handle of the knife and causing corrosion. It's not really a structural joint. But the solder Randall uses, and that I have worked with melts at over 1000 degress, and forms a very strong structural joint. Do I think it's important to have a mechanical fastener? Yes, it will always improve the strength of the joint. But don't underestimate the strength of a good soldered/silver brazed joint. They can be quite strong.

One of the reasons makers will run steel a little softer, as you mentioned the A2 in Reeve's knife being run soft, is that the steel is tougher that way, as it will bend before breaking. Hopefully. An added benefit is that it makes field sharpening easier. These are survival knives, after all. If you ever find yourself in a bad situation and the knife gets dull, and all steels will, it is just my personal opinion that it is better to have the steel a little easier to sharpen. Obviously you don't want machete hardness, but it will also take "hard use" better as well.

Good points and good questions.

Sam,

You need to write a book. Let me know when pre-orders are available. :)



I seem to recall that they used to make the tangs longer at some point. They kept shortening them until they settled on around an inch or so, for length inside the tube.

You're correct, Sam.

it's important to remember that this is a combat knife, and to my knowledge, never designed to be batonned or beaten on.

When the knife was designed in the early 60s, the only batonning around was a girl's activity.

Even so, many have been, with this being the only failure that I am familiar with.

There is a guy on another forum that batons the snot out of his #18 and the knife just shrugs it off like a bad habit. The only failure has been the baton itself. The sawteeth eat the wood baton like a snack.

Lol, a girl's activity! Tell that guy to feel free to post pics here. As far as a book, I'm definitely not qualified for that, but I have thought about writing a monograph on HH knives. Not that I'm qualified for that either, but it would be a lot easier!

I'm not surprised about the #18 taking the batonning, though. Good silver braze joints are very strong.
 
The older #18s were O-1 tool steel right? I'm definitely wanting one to try. That may be my one Randall

Mist, I'm not a Randall history guy, but I believe that their carbon option has been O1, and for SS they have used 440B/440C. I think it has been that way for decades, so I don't believe being older will make a difference. TAH is a big Randall guy, and would know more. He will probably see this and reply anyway.
 
Mist,

Sam is correct. #18 blade is either O1 or 440B. Both are hand forged. 440B is a $55 upcharge.
 
Thanks guys, I was under the miss-impression that they had stopped using O-1. That is great news :)
 
Thanks to this thread, I've committed to a Model 18... After all, just how many holow handle are being made out there? Outside of full customs, I know of only two... The Randall and the Boker Apparo... Pretty soon I'll have both.

I like the idea of production knives, because they can easily, and most of all quickly, be replaced, which encourages real use compared to more involved month-long/multiple emails tractations... I also very much like old out-of production factory hollow handled knives, but these not so much for use...

I'm hoping for a Parrish, which has become my new grail knife (over the much easier to get, and quite original, but flashier and less fuctional, Al Mar SF-10), but I just missed out on a very cheap dead-mint Parrish on Ebay (went for barely $800, probably 50% under value, and within my reach, aaargh), because if you choose to sell using Ebay's "Global Shipping Program", be advised that the word "knife" in the product's title -in Ebay's spout of political correctness- is now associated with selling weapons, and so all international purchasers that you force to use your "Global Shipping" option will be blocked out from where you are without any notification to you... And once you have chosen "Global Shipping", I think you can't undo it without doing a whole new listing.

Using regular international mail, and avoiding the word "knife" in the description, should avoid you this travesty.

If you think I'm kidding, consider that lately the only thing I've been able to get from the US into Canada, within my range of interests, were daggers with "dagger" in the title... And I was wondering: "How come I'm getting a lot of daggers these days!?"
