Steels...

[Taz]

Well, my grizzly didn't arrive in time for me to grind on my college break, but I did do some hand filing to flaten out some of the convex grinds. I am also looking for new steels to work with. I have used O-1, 1095 and A2 and was wondering about the planer blades of Cobalt and M2 from Grizzly's catalog. Will these make good knives or is the M2 not impact resistant enough? Also, how can I anneal these planer blades..they come at 62 to 64 RHc?

Also, is CPM 3V available anymore and where can I get some to try? I read the review of Jerry Hossom's espada (sp???) and was very impressed and liked the look of that smaller knife he did. I was wondering where I could get some 3V because I am looking to make a few kitchen knives for myself and it seems like it would be a good steel for that. Any ideas??

Also, how is 3V, 420V, 440V (ie the "CPM supersteels") and ats-34 and 440C to grind compared to the steels I have used? thanks guys!!

Well, the cobalt planer blade is not a steel and from my understanding has to be worked as is, just like talonite.
The M2 can be anealed and is a tool steel thats supposed to rust like hell if its not coated, but resist wear very well. And I guess its pretty tough since most M2 blades are about 2 Rc points higher than ATS34.
ATS34 is good stuff, works easily by hand or with a crappy grinder

(my 4x36 gives me lots of experience in that area) And you end up with a good blade overall too. Not great in any one respect but good in all fields, including toughness,edge holding, and resistance to corrosian.
I don't know much about the CPM steels other than they're supposed to be super wear resistant. Even anealed, they have enough vanadium and other stuff to make them take a while to grind. But once your done their supposed to hold an edge for a long time.
Hope that helps.

If I got anything wrong hear I hope you guys will corect me
