Forged or stock removal Let's dispell the myths

Joe,

My MS stamp does help, but it certainly isn't a ticket to the big time. If anything, it places alot of attention on how you do business, and customers watch for that huge price increase after receiving the stamp. I do forge CPM3V, and do charge more for it, but it is still not as big a PITA as forging stainless for me. There are alot of marketing issues here too...like no one has ever requested a forged stainless blade from me.
It's hardly any different forging stainless than it is 3V or D2.

Edit: I forgot to add an interesting fact, though: the mill that rolls Crucible's steel says that it is easier to roll CPM steel than conventional. CPM-154 is much easier to roll than 154CM.

Interesting that you mention D2. I have heard smiths refer to it as the "almost stainless steel". I saw the specs and it has like 8 times the chrome that 52100 has. How much chrome does steel have to have to be considered "true" stainless? To me, 12% seems like an awful lot and the 18% that CPM60 has is just a HUGE amount to my mind. Is the Crucible stuff easier sharpen? I have never done any sharpening on my McWillaims other than just a quick straightening of the edge on a crock stick because I got out of the reserves right after I got the knife and never used it much. It was my going replace an SOG Tigershark to be my large field knife
My experience and my brother's with Benchmade ATS34 folders is that you better take them up on that "lifetime sharpening" offer....That stuff is harder than an Amish teenager in a strip joint......lol

It doesn't really matter (within reason) how much chromium you add, you have to balance the carbon and the chromium. After heat treatment, D2 has something like 5-8% chromium in solution, depending on heat treatment and chemical makeup of the D2. You want 10% or more (the number varies depending on who you ask) for corrosion resistance. As for people saying that D2 has the best of both worlds, being nearly stainless and being a carbon tool steel, it's all nonsense. D2 has all of the disadvantages of a typical stainless steel (large carbides, fairly low toughness, hard to finish, etc.) while not having the benefit of actually being stainless. I would argue that AEB-L, a stainless steel, actually shares more similarities to carbon steel than D2 does.

Edit: S60V having a very high carbide volume, and much of it being vanadium carbide, it is definitely not easy to sharpen. Also, it is best to take it fairly soft, 56 Rc, which makes things more difficult because of the edge rolling. S30V is easier to sharpen than S60V, but still relatively difficult compared to carbon steels or, say, CPM-154.
 
another silly newbie question . Why do the cutting edges edges of many stainless knives that have standard edge bevels look like they have been taken down with a 120 grit belt?

I have read that the cut-off point for a steel to be officially considered stainless is 14% chromium content. But I agree with Larrin when he says that the element balance is what determines the actual corrosion resistance. From my experience as a user, some stainless steels (ATS-34, S30V), take a patina about as easily as CPM 3V and D2.
 
I care more about the finished product than how it was made,as I collect & own both types of knives. If I see a Forged Bowie or Fighter that I Really like,and a Stock Removal Bowie or Fighter that I kinda like-The forged knife is the one I'll end up getting(or Visa-Versa).Maybe I'm wrong about THIS Part,but Forged knives DO seem to be lighter and quicker than stock removal knives.I don't know alot about steel,RC hardness or most of the other technical aspects of knife making discussed in this thread-But I do know what I Like.Great Thread Bailey,I've learned alot from this one & Steven's CNC thread.
P.S. Matt you keep on Forging away-I Really Love your Bowies & Fighters.:cool:

that raises another interesting question. When I think of a lot of stock removal blades, i think hollow grind like Bob Loveless, et al. Some are`what imight call a hybrid of the hollow and sabre grind....hollow ground but with a bit of flat toward the spine. Now i know that you can taper the center ridge of a hollow ground dagger but can you fully taper a hollow ground single edge blade and still have it come out looking right?
 
In Short, Yes. Lets dispel another rampant myth. All forged blades aren't flat ground. All Stock removal blades aren't hollow ground. All forged blades aren't distal tapered. Not all stock removal blades are flat sided. Both camps make knives in both styles. Neither have an exclusive on either style. I see a very strong trend here to assume that if it is a flat ground blade, that it had to be forged. Nothing could be futher from the truth. There are millions of Case, Schrade, and tree brand pockett knives out there that have been made over the last century, that never saw a hammer. I have personally forgen, and them hollow ground many knives. My great Grand father forged. My grand father forged, and I have in the past. It's just not the way I do things now. We all have our own way of doing things, and what we like. some one said earlier that D-2 isn't tough. It is industrial Die steel. In this use, it is the # 1 steel in the industry. Why. Because it is highly demintionally stable in heat treat, and exceptionally tough. It can with stand high abrasion and repeated impact better than just about any other steel currently in use. Yes there are others, but it is #1. If it can cut and shape tons of steel daily. I think it can handle a few deer, and tree branches. This isn't rocket science guys. These are only knives. Tools. Pure and simple. And not particurally exotic, or hi-tech ones at that. A tool, or knife made by either camp will do just fine. I'm finding it hard to understand all the hoopla. Mike

Mike, from my own personal use, I agree with you that D2's toughness is not a problem in use. But you also said that it is #1 in impact toughness. What do you think of the Crucible spec sheets that say otherwise?

This one here states that of the knife steels tested, CPM 3V, A2, and CPM M4 all have higher impact toughness than D2: http://www.crucibleservice.com/datash/ds3Vv5b.pdf?CFID=964518&CFTOKEN=41731767

This one here states that O1 is also tougher: http://www.crucibleservice.com/datash/ACFC3C.pdf?CFID=964518&CFTOKEN=41731767

And this one here states that S30V is tougher: http://www.crucibleservice.com/datash/ACFC3C.pdf?CFID=964518&CFTOKEN=41731767
 
No Sir! I did not say that it was # 1 in toughness. I said that it was the # 1 most used Die steel. And it is used more than any other in the business. That is not to say what is the toughest. I would think there many contenders for that title. To say that it isn't tough, would be a gross understatement. It is hell bent for tough. I have a hunter here that was a prototype for the knives I made for Ted Nugent. The blade is only 3/32 thick, and heat treated to 61 Rc. It is deeply hollow ground, with a tiny spine. In testing, the blade wan bent to failure. It is cracked from the edge, to 3/4 up the blade to the spine. Most steels would have snapped on the spot. I have been using it in this condition for over 15 years, on many, many hunts. The edge is only .010 thick! All this without a differential temper. That's tough. And really makes me wonder just why we need a differential temper on a 1/4, and many times 3/8" thick spinned knife. If this isn't strong enough with good straight forward heat treat. It isn't a knife we need at all. It's time for a recking bar. You have already passed what a typical pry bar can stand. I think all this is for bragging rights to our buddies, more that any practical value. Add to this thatt many differential tempered knives would fail from bending so easily, that any benefit is totally lost. If it takes 30- to 50-lbs to bend a knife, who'sedge is probably going to crack any way,when differentialy tempered, compared to 100 lbs to 200 lbs, before sustaining any dammage, due to full tempering, where was the advantage. Most knives that can bend, due to an ultra soft back not only dont have very much practicle strength, The edges are often so soft, to keep them from breaking, that they are far below what is the accepted norm for edge holding. I want a knife first, and can't accept this compromise. if i want this type of edge holding, I would go to wally world, and buy something made of 440-a, Or AUS-6-8. But I will not produce such a knife. It's just not why I make knives.

Amen! :thumbup:
A2 is even tougher, if you need it. :)
 
Mike, I agree, D2 is definitely tough enough.

Amen! :thumbup:
A2 is even tougher, if you need it. :)

Phillip, I agree here as well. And CPM 3V is even tougher than both of them, and more wear resistant than both as well, according to this spec sheet: http://www.crucibleservice.com/datas...TOKEN=41731767

I hve a kitchen knife made from 3V, and it has been great. It is ground real thin (about 3/32" thick at the spine with a full flat grind), but it hasn't chipped out or lost its edge at all, and I've been giving it a good workout for the last 3 months or so.

I agree. My Moran Airman has a slight taper (nothing like the full taper of his later knives) that "hybrid grind i was talking about kinda like a Randall, a deeply ground clip, a slightly hollow main bevel grind AND a convex edge.....the complete entertainment package.
:D But I think you might have a bit more trouble doing a bowie full hollow grind all the wway tp the spine like a Loveless hunter, with a fully tapered blade and the deep clip. Maybe not, but maybe the past makers have kinda trianed my eye to expect a certain type of knife to have particular grind characteristics. Now I will say this. I was talking to a MS (the guy from London who used to work at the Tower...can't remember his name) and he said that one of either his JS or MS knives was hollow ground. When it was being judged, he told me that B.R. Hughes said that " this is a very fine knife, but I just don't like hollow grinds on forged knives". Obviously it passed muster, but it was interesting to hear about some of these preconceieved notions and preferences/prejudices. That may not be an commmon one in the ABS if you look at what most of the smiths are producing.

This occurred to me. I have seen a lot of very fine stock removal knives that were much thicker than I thought they needed to be, particularly tactical knives. i wonder if the forgers have such an absolute faith in the inherent strength not only of the forged blade using the differential heat treat techniques, but also the characterisics of the distal taper that they are more willing to taper those blades out to where they are pretty thin on the tip and as a result, feel really light out front? I took one of my early knives to the local knife show and one guy who handled it was very surprised at how light it felt in his hand. Now admittedly, My poor grinding skills had led me to leave it a bit thinner overall than I wanted for an 8 1/2 bowie, but it was tapered all the way out and this guy noticed it after handling equal sized stock removal blades. And he didn't comment on the fact that it might have been a bit thin, so maybe that was more me being slightly dissapointed that it din't turn out exactly the way I wanted.
:D And in repsonse to the ease of sharpening comments, it was made from 1080 and was incredibly easy to sharpen to a very nasty and durable edge (it would have passed the ABs 2 x 4 chop and shaving afterwards test requirements because i tried it) even with my bad heat treating, sharpening and grinding skills at the time (they still aren't anything to write home about, mind you...lol). I still have that knife. One guy asked me what I wanted for it but I refused to sell it because it was flawed in the fit and finish department in my opinion and had my name on it...lol. The primary reason was it was one of those serendipitous knives that all of us have made early on where we can't figure out how we did it, but it works! Another thing that has been mentioned here is that you can do the sole authorship route, including all of the heat treatment, much more easily and more cheaply with forging when you are getting started. i built the infamous Goddard one brick forge like a lot of guys.:thumbup: Unfortunately, that whole "$50 Knife Shop" vibe morphed into "shop worth more than you current automobile'" fairly quickly.....and I still not that good...LMAO

Tactical guys are out in their own little world sometimes, but again you're just making generalizations. Phil Wilson is a good example of a stock removal maker that makes thin, flat ground, distal tapered knives. If I were a tactical maker I'd be worried about guys ramming the tip through car doors and chopping through cinder blocks, so I'd probably make them pretty thick too.

true dat.....or "testing" fully hardened blades by using them as tree stand "ladder rungs" There is a guy in Sarasota who CNC mills integral tac knives from L6 I think and they look like bricks. Tough as hell i'm sure, but they have to weigh a TON!!!!! The WORST offenders are the guys who sell hundreds of pretty shiny swords at the Ren fairs out of a booth the size of a mobile home...lol. All you have to do is go over to the table where the lone maker has a couple of REAL swords, be they forged or properly stock removed and pick one up to tell the difference.
