Jerry let us know how that new steel works on a dirty old hog.

Talked to Jerry last night. He'll give a report on the knife and steel upon his return. (He got the steel from P.J. Tomes who uses 12C27 for his stainless knives (for those who don't opt for his excellent forged 52100). Jerry doesn't use the same heat treat as P.J. but from his description it sounds like he wrung what he could out of it.

Anyway, we should have our answer in a few days...
 
Jerry's LB-5's are great light carry folders. I don't have many lockbacks, but sure glad I have this one. This was his first with a modified spearpoint blade, and Jerry had it in his pocket when I purchased it at A.G.'s show. We were both happy. :thumbup:

Look forward to hearing about Jerry's take on the new steel. He sure does 154 right.

That's a nice one, Joe. Some months (or maybe a year or so) back I had sent Jerry some images of various modified wharncliffe and spearpoint blades and suggested that he add them to his lineup to go along with the more common blade profiles he had been employing on some of his folders and straight knives. Looks like a winner to me! :thumbup: :cool:
 
Joe, the only worry I have when carrying the ultralight LB-5 is remembering it's in my pocket. I asked Jerry to be sure to put a lanyard hole in the Winchester lockback.

When you get old, you forget stuff :)

Well at least you remembered that. ;)

I can see Jerry's gonna have to incorporate some new retention hardware with his knives...

Got a phone call from Jerry this morning.

He had an opportunity to use his new prototype with the 12C27 blade steel this weekend on a hog as well as some general cutting around the camp.

As I suspected, Jerry said that while the blade takes an amazingly sharp edge (due to the fine grain structure), the edge was not quite as durable on heavy/demanding cutting tasks as those blades featuring CPM-154. (More testing will conducted utilizing various blade geometries to try to get the "best" out of the steel.)

So, while Jerry feels that the steel is just fine for most any task, it just falls a bit short on the retention side though it readily sharpens back up to a hair popping edge with just a few licks of an ultra-fine diamond (or ceramic) hone. (Proving once again that there is no perfect steel, only a set of compromises as one seeks the balance one is looking for.)

Jerry said he may try to log on later and post additional comments as need be.
 
My overall impression of the 12C 27 was what I would call favorable, but even with a little different edge bevel and possibly a different heat treating, I don't really believe that it's going to perform better than CPM 154 CM. I find that the 154 has a better balance of properties for the way I use a knife. I know I'll be using it again in the near future and if I find anything revealing, I'll keep you posted.
 
I just received this one today from Jerry. He calls this the Rounder and it is available in two sizes. This one is the smaller of the two and it is 3 5/8" closed. Scales are elephant ivory with a bomb shield inlay, blade steel is CPM-154. Available in slip joint or lock back. I'm sure this will be a very popular pattern.
 
I like that pattern in the 3 5/8 size, and ivory to boot! Nice one, thanks for sharing.

That's a great looking "Rounder". :thumbup:
