Model 10 from R. W. Clark in Liquid Metal (LM1)

Sure. However if the same factory provided a car similar to yours and said: go ahead try to crash it, because you can't and if you do we'll give you a new one it would've been a different matter.
 
"Would love to see some affordable production neck knives cast from this material someday."

Oops, almost forgot. I was talking to a company at the Blade Show about that exact product. It was to be a skeletonized neck knife at around the $50 mark (give or take). Not sure what has become of the project (too much happening to monitor it all) but the LMT reps were talking to him.

I will follow up on this one to see what became of it. Heck, if its not moving I may jump on it. The knife in question did fit within the current volume limits.

Could you please do all of us a favor and place those misplaced scientific terms then? And why the statistics are BS? Shaving sharp is more descriptive perhaps?


rather read how well a knife cuts open feed bags, whittles tent spikes, picks a splinter from under your skin, cleansd small game, prepares a meal, spreads peanut butter etc,
Well, I've never had to open feed bag or clean a game, and I am not sure I see the value of peanut butter spreading test with a field knife. But if you post results of such tests performed by you, I'd be very curious to read.

instead of "the knife seprate the matter of the quantum substrate using 123 gigga foot pounds of force applied along a linear axis"
Doh. When I read his reviews I see cardboard, wood, various rope cutting tests. Stuff that I can get myself easily. Are you sure you were reading his reviews at all?

(not a real quote, but may as well be.)
Of course it's not...

For crying out loud, it is a knife. A sharpened hunk of steel. People have been using them for thousands of years.
And your point is what? No research & development is needed in the area?

were sharpened to the wrong included angle and they were using the wrong steel. Forget that they had been doing it all their lives and it worked fine.
In other words it doesn't matter at what angle you sharpen? Somehow I am sure they knew it did matter :)

Well, if I was ewver going to write a knife review, I would just use a knife and wrote about what I did with it, for stuff that I usually sue a knife for.
Thanks in advance. Reviews are always welcome here, well as you can see not always.

IF you have to come up with salt baths and concrete chopping to test a knife, you might want to re-consider what a knife is for.
Is that all you read in those reviews? Out of few dozen reviews concrete chopping is mentioned in 1 or 2.


Further, how much money you spend don't mean squat.
:) Sure, when it's not your money.

I have a ten year old Swiss Army knife and a Old kitchen knife from Old Hickory that will outcut just about every high dollar custom knife I have ever seen.
Now that's a bold statement, or else you haven't seen much. And you said Cliff "makes broad claims about materials, of which he has no real knowledge"?
So, what about those custom makers you were so concerned above, all their life's work isn't gonna cut better than your 3$ knife?
 
Hi Mr. Gator97. I have seen your website. You take real pretty pictures of knives and drive a fast car.

You seem to write real good too.

Maybe you should write knife reviews too. Oh, wait you do, all about Busse knives right? Have you used any of them? What about all those other fancy knives you collect, do you use them?

Knife collectors are a funny bunch, they got all this shiny steel sitting away. Where I am from, you got a knife, you use it. My Pappie carried the same pocket knife for ten years. Whittled a lot with it too. Every night after supper. Always kept it sharp. It was lost after he died, couldn't find it. I wish I could.

That knife would mean more to me than any custom knife.

Bill Moran carries an opinel that he wire inlayed. Nice knife. Cuts well too, I bet.

When you pay big money for a knife, you are paying for a name, pride of ownership, high grade materials (some quite expensive), and most off all the knife makers labor, effort and creative design.

I gotta a couple of Bob Dozier's knives. Great for skinning out rabbits. As much as I like them, a simple paring knife from Kershaw, opinel or victorinox will cut better. Won't hold an edge as well, but sharpens easier.

It is nice of you to come to Mr. Stamp's rescue though, kind of like a knight in shining armor to the damsel in distress.

I'm new to these parts, but it seems lots of peoplpe see the same thing I see, a lot of undisclosed bias and bullcrap being asserted as science and truth about knife performance.

I may not know as many fancy words as you esteemed fellows, and I never did take to schooling like you folks seem to, but you can't piss on my roses and try to tell me it is raining.
 
I've been following this thread since it began. I've never been one to be on the same side of the fence as Cliff. In the case of Liquid Metal, I have to agree with him.

IMHO, LM1 doesn't hold a candle to Stellite 6K. I purchased about $200 worth of LM1 and actually have one in my pocket right now as a test knife. I made 3 others and frankly, for a folder, it sucks. The detent ball is the biggest problem. A hardened 2mm ball cuts a groove in the blade in about 2 openings. Hard to sharpen and the edge isn't much to brag about. In my cutting tests, Stellite 6K cut quite a bit longer on rope, webbing, and especially cardboard.

I agree that Cliff tests knives in the extreme and have a hard time with that. I test them on a daily basis, cutting shop stuff. I am not happy with LM1 and have no desire to sell the folders I have made with it to my customers. Stellite 6k, on the other hand, goes out of my shop on a constant basis with a whole bunch of satisfied customers.

I'm sure RW will refute my testing and results and that's ok. All I can say is that I've been making knives for 32 years and I have used and tested more blade materials than his age, and LM1 isn't for me.

I wish RW would have spent as much time responding to his bad commments about the Knifemakers Guild that a number of us members asked for than to be posting on this thread.

I must admit, I haven't made a fixed blade in LM1 and don't plan to.

I have to no desire to get into a peeing contest with anyone. My results are my results. No amount of posting and will change that.
 
i've always thought the main selling point of LM steel is that it can be cast with a sharp edge? Therefore making it an excellent material for mass production? Using it in custom knives? Thats a different story, theres a time and place for each type of steel and from what I've been reading it seems like LM is more fit to be in knives that are mass produced?
 
According to LMs materials, you can cast it with features down to a micron.

The manufacturing costs of putting on an edge would be dwarfed by the costs of the material in comparison with typical knife steels.

You would probably want to find lots of other micron level features to cast that would be impractical or impossible to machine using traditional methods.

A while back I tried to come up with some ideas as to how you could use the castability of LM1 at the original Liquid Metal thread:
  • Very complicated edges (e.g. "fractal" serrations)
  • Honeycombed or monoque blade structures
  • Replace titanium in composite blades like the Strider Badlands Bowie or Walker Zipper blades
  • Radial multi-edged blades (e.g. 3 edges, 6 edges 20 edges ...)
 
Kit, sorry that you have had bad results with LM1. No reason for me to argue it with you, your testing methods are not in question. To each their own, no biggy. It did not work for you but it has been working great for me. I have been getting nothing but positives from my customers:confused:.

I am in the process of making a batch of new liner locks right now. The past LLs have not shown the problem with the detent but I did see it in Atlanta with a few frame locks. There are new materials coming up the pipeline with much higher RCs. If they pan out as good knife materials that may fix the problem. One question though. Why does Talonite not have the same problem when it is even lower on the Rc then LM1?

As to how long you have been making knives. Yep, I have only been doing this for 13 years. Guess I am the new guy on the block:rolleyes:.

As to the guild thing. You wanted me to name names. Why the hell should I? They were private conversations. I did not list out any of the things that I was told, so there is no reason to name sources. I don't like the guild. Big fat hairy deal! I am not telling anyone not to join. I just want them to think about what the guild is offering for their money. If they feel that it is in thier best interest then they should join. End of subject.
 
Kit, would you be willing to send one of those blades to me for a week or so. I want to get Jerry to shoot a photo under his electron mircoscope. There has to be something going on with the material itself for such varied results. I want to compare it to photos of my tester model 10.

Nothin' like a little self deprecation, followed up by some back-woods wisdom, to set the tone.

Posts by newbies are always quite revealing. And we lucked out and got digger1's first 6 of 6 posts right here in this thread. Digger1 busts out... nice work digger1. Your contributions are certainly ...

Keep on postin' digger1. Or should I say, "keep on diggin".
 
Kit, thanks for some additional, alternative perspective on the current versions of Liquid Metals.

Why NOT challenge Kit's methods also? I mean, fair is fair. Bias is bias.

I'm not a maker. But you may have pegged it... the relative hardness difference could be one mechanism that is causing wear preferentially on the LM1.
Originally posted by R.W.Clark
One question though. Why does Talonite not have the same problem when it is even lower on the Rc then LM1?
Good question. Talonite/Stellite is loaded with hard carbides. Very high abrasive wear resistance of Talonite/Stellite might be part of why it holds up to a harder ball detent's wear.

A ball detent kinda does two things... a liner lock's spring tension causes a "vertical" load into the flat side of the tang area, like a low pressure Rockwell indention tester. But the ball detent also drags horizontally on the tang under that spring tension load, which would be more of an abrasive (dragging) wear mechanism.

So LM1's ball detent problem could be more about wear resistance than hardness (using Stellite comparison), or both. But boosting hardness could solve the problem. (Unless the LM's have low abrasive wear at any hardness.)

Maybe LM1 folders need to be made with spine/rocker locks (would still think wear would hurt lockup), or with a lock resembling the Axis lock that just uses a bar against a sloped tang notch.

SIDEBAR
I know that when we have erosion problems with industrial control valves (high pressure drop and/or abrasive particles whizzing through a valve), Stellite (6K usually) is an early choice in preventing control valve trim erosive destruction. Three reasons for choosing Stellite:
1. 6k is tractable to weld onto (overlay) carbon steel and 300 series stainless, and has similar thermal expansion characteristics so it doesn't flake/crack off when it cools, or undergoes thermal cycling in the valve.
2. 6k is typically very good against corrosive attack of many materials, and sometimes the combination of corrosion of the external oxide film exposes underlying, less tough substrate for erosion. Double whammy.
3. 6k is very resistant to abrasive wear, out of proportion to it's Rockwell C indention hardness... soft matrix filled with hard carbides, but somehow that soft matrix must cling to it's outer oxide layer and/or the carbides in a manner that resists abrasion nicely.

And if Stellite isn't a good choice for some reason (e.g. corrosion or matrix breakdown via amine content of fluid), guess where we head... solid 440C hardened trim (usually upper Rc50's to Rc60), or upward to a chromium carbide or a nitride coating, or onto ceramics or tungsten carbides.
 
R. W. :


Now I am not holding it right?

It wasn't the way I said I could break it no. That is kind of critical.

[comparing two unspecified reviews]

Second, they both sport Kydex carry rigs. Both are clamshell style. Cliff only mentions the good points of the Busse rig (ie no rattle, good retention, and nice leg loop). But in the review of the clone Cliff clearly states that he dislikes Kydex for its low durability in heat extremes. Why was this "negative" not mentioned in the Busse review.

If this is the SH-Battle Mistress review, because it was wrote many years earlier before I saw brittle failure with Kydex. The newer reviews such as the Camp Tramp reference the inherent problems with Kydex in this regard. I have also made those statements on the Busse forum here. There were also pictures of my shattered Basic sheath in the reviews forum and on the Busse forum. But yes that should be part of the review, it was just updated.

First the edges of the Busse and the Clone were only 0.001 apart in edge thickness (and the Busse is thicker). But in the reviews Cliff states that this is the ideal performace edge for the Busse, but then states that it is to thick for the clone

That would be a problem if the knives were intended for the same use, Busse generally allows use which other makers are less than positive about which would obviously then indicate different optimal edges. Which two reviews were you looking at exactly. For pure wood working and other lighter tasks the Busse edges are overbuilt for most, this is noted in the reviews and I have said it on the forums.

By attacking my fit and finish right off the bat ...

I actually thought that was actually more positive than negative considering the whole of what was said. Note the Busse reviews also contain such statements, the Howling Rat sheath was a little loose, the Camp Tramp tight, and both the Howling Rat and Camp Tramp didn't have 100% optimal sharpness edges and there was also variance in edge thickness and angle. The BM-E has a raised tang. The SH BM had a sharp choil (and to a lesser extent so did the Camp Tramp).

[just to clarify the Howling Rat and Camp Tramp are Swamp Rat knives, not from Busse Combat, but could also be called Busse knives since his wife runs that company]

Digger :

My family is farmers

So are mine on one side, fisherman on the other.

I would much rather read how well a knife cuts open feed bags, whittles tent spikes, picks a splinter from under your skin, cleansd small game, prepares a meal, spreads peanut butter etc,

Those kinds of things are in there along with the stock testing.

Jeff :

It is possible that there is something new to be observed with this amorphous solid if you really work on a fine edge. Since the material is sort of soft I would try stropping it with ferric oxide (jeweler's rouge) as one of the experiments. I would try working on it with hones and strops that are made for sharpening straight razors.

It is soft but doesn't always behave as you might expect based on its softness. For example at 50 HRC is does not file near as readily as a SAK (or other similar knife). You can file it, but the file does not bite in as readily. Is jewlers rouge even finer that CrO? Maybe trying it out on clean leather after CrO. However when I have really tried in the past to get such high levels of polishes on steels, I never really found a limit and could get even "bad" steels like ATS-34 to be very sharp, and approach true razor sharpness (the double sided disposable ones you buy).

It might however be interesting to compare sharpness at various grit levels. I have sharpened this knife now completely six times, extensive sharpenings, removing a micro-bevel each time, and it does get sharp fairly easily. Freehand I can consistently get shaving edges with just a 1000 grit hones. I was really impressed with this until I tried the same thing on a steel knife and it behaved the same way. As a positive side effect of all the sharpening I have done lately my freehand skills are actually half decent now.

Kit :

[LM1]

Hard to sharpen ...

I have sharpened this one a lot (waterstones + cro and ceramic and diamond rods), and if anything I would call it easy to sharpen if anything. What abrasives were you using, belts and a buffer?

Back to the knife :

I have done some heavy whittling, the performance is solid, very close to the Pronghorn (which is an interesting contrast). It easily out cut the Howling Rat (with NIB geometry) due to the thinner edge and more acute primary grind. It also doesn't need to be used in a choked up grip for near maximum power because the sharpened edge goes full back to the handle so there is no leverage disadvantage. There is a problem with ergonomics in that use however as the handle is a bit flat on the underside, no curvature, it just goes straight across. This induces a little "squarness" which would ideally be removed.

A note on sharpening and hte lack of a choil. It is often said that this makes sharpening difficult, and it can depending on the method, if you use v-rods it has little effect, but on freehand sharpening not being able to bring the stone back to the start of the edge does require an influence. You basically have to hone the first cm or so separately and then do the whole thing. Not a big deal and for me greatly out weighs the negatives of choil notches like hangups.

Also used the knife with a high polish for some light vegetation cutting, it worked well. The main problem here was simply lack of reach, and for the heavier stalks, not enough blade balance. Most light work was more productive with the blade pinched sideways and the material cut with a flick of the wrist. No problem in getting the blade very sharp so it cut all that kind of light stuff very well. Tried it out on some soft woods also, mainly Alders. It could easily chop them down readily (small woods, under an inch), but slightly harder wood of decent sized to make shelter would require the use of a baton to make it efficient.

Just as on the turkey, the thin point proved to be efficicent on some fish. It was a little large for the fish I ws cleaning (some trout), but still easy to handle due to the low weight. Not having to be so careful about corrosion after the cutting is a decent bonus as well - though this you can get with a decent stainless of course.

R.W. Clark,

If LM1 and the newer, harder LiquidMetal products coming down the line are castable, then I think that Cliff's reviews of your LM1 Model 10 are very worth noting and recording. Knowledge of what the knife does and doesn't and under which circumstances these behaviors occur, while being good for the testing of any object, will be very important for completely cast blades, tangs, and future folding knives.

With casting, expertise in flat grinding, hollow grinding, and slackbelt grinding will be irrelevant. With time, the design of the knife need not be done by an actual knifemaker, but rather anyone with artistic talent and some experience with geometry. Since completely cast blades are the future that you foresee for Liquid Metal, maybe studying the works of noted, Canadian knife abusers (I say that we here in the USA can ruin just as many just as bad!) will help advance the Liquid Metal revolution.

And if I'm wrong, that's cool, too.
 
thombrogan :

With casting, expertise in flat grinding, hollow grinding, and slackbelt grinding will be irrelevant.

This assumes that the cast materials can compete, as of now they can't. The comparisons made of LM1 compare it to other cast alloys in which case it does very well. However when compared to alloys that are not so restricted, it has no materials advantages outside of corrosion resistance.

It would be fairly nice though to have a cast material which was just even with traditional steels though for the reasons you noted. Imagine just at the start of having a near 100% elimination of QC issues with geometrical variances. Not to mention heat treating which I assume is probably more consistent.

Before anyone gets too excited about LM1 and revolutions to casting in knives, Boye has been using cast steel for years and more recently cast cobalt alloys. They work excellent as light use cutting knives, not very flexible or anything in the impact toughness department, but for hunters and light utility knives they are great.

:eek: :eek: :eek:
 
First off, not picking sides here! :)

Ron, my piece of LM1 is NOT harder than the Stellite 6K and Talonite samples I just hardness tested on my Wilson hardness tester. The LM1 tested multiple times at 49Rc, the Talonite tested multipe times at 49Rc, and the Stellite 6K tested multiple times at 50 to 51 Rc.

LM1 at 49 Rc can be fairly easily notched with a sharp file, Talonite and Stellite were barely scratched using the same file and procedure. That is taking the file and using a sharp corner cutting a notch in the material. LM1 notched, Talonite and Stellite did not. To me that explains the trench cut into the LM1 by the detent ball.

The thing I really dont like about LM1 from a makers point of view is the low working temperature and the Be. in the matrix. I like being able to hog on Stellite and Talonite and not worry about ruining the material even if it gets red hot. I hope to see this material with a higher hardness and no Berrilyum and give it another try. Of course that is just me, and other makers opinions may vary.

There are over 100 knife reviews on my site, and Busses are around 20% or less. How is that "all about Busses" anyways?

Have you used any of them? What about all those other fancy knives you collect, do you use them?
Most of them I've used at least once. Due to sheer number of knives I can't physically use all of them intensively, especially that my job is comp related.

Knife collectors are a funny bunch,
Well, what can I say, whatever U think. I like collecting knives and by the way it's a primary way of supporting makers.

It is nice of you to come to Mr. Stamp's rescue though, kind of like a knight in shining armor to the damsel in distress.
For one Clif doesn't need any defence, two my message was to you.

I'm new to these parts
Yes, and first 6 messages from you are all in this thread, all flaming.
 
R.W.Clark :

However, Cliff is an abuser to the highest degree. His goal is to break knives.

To illustrate how skewed such a viewpoint this presents :

Out of the knives reviewed, under 40% were broken (counting the two I made on a lark and broke). Not even the majority.

Out of those, 40% were specifically asked to be broken by the makers / owners of the knives. They knew the knives were going to be broken and wanted to have them compared to others.

Out of the remaining knives, all except for a few broke under the described intended use of the knife, that can be debated in a few cases as the intended use of tactical / survivial knives varies widely.

So the above statement which implies that every knife is broken in a manner widely outside the scope of work, and in opposition to the maker / manufacturer is more than slightly off.
