Cpm-3v

Which is better CPM-3V and ELMAX? I heard that ELMAX is pretty tough, has great edge retention and also were stainless.
 
Agreed...

I have a CPM-3V "Strong Boy" planned.

Phill would approve :)
 
The Elmax is a super quality steel than can take a high hardness without cracking or chiping at the edge. As well it is a stainless steel. Frank
 
JB....I agree! Yes it is, brother. Now, when am I gonna see a pic of what you just made with the stuff? :D

shqxk,
Elmax is a great powdered stainless steel, in my experience on par with CPM 154 but maybe a bit more edge retention. Don't confuse edge retention with toughness though. If you look at the charts, 3V is leaps and bounds beyond Elmax in toughness! I don't think Elmax can compare with 3V in the toughness department, the 3V is just too badass. You can give it a nice fine edge, then hack through some aged oak and strip wire with it for a few hours, and it will still shave your arm hair. It's in a different class.
 
I had a buddy chop two 8" trees with Elmax, and then slice paper. I should have had him strip wire! :)
That CPM 3V looks killer and may be on my kitchen list soon. I think its a stainless vs. non decision. I think you are right, Jon. For toughness, high carbon is going to win.
 
I like a lot of different steels, but CPM-3V is just about perfect.

I made this one for a client. Before I put the slabs on I did stuff that you shouldn't do with small knives. I chopped through several pieces of 3/8" dowel by striking the spine with a dead blow. I did get a small chip, but it still cut through several strips of 10 oz. leather and a bunch of cardboard. I haven't used it enough to play with the heat treat recipe, so I went straight by the charts and got 58-60 Rc. Also I had to use a stronger solution for the acid etch compared to A-2.

I will soon undertake the arduous challenge of crafting my own knife for the first time....snd after many hours of research I have chosen cpm 3v as the medium for my masterpiece ...I hope .I could really use any helpful suggestions or input on this topic. This is officially my first. Post on the forums as well ...Gosh I'm excited :)
 
"For pure performance, CPM-3V is the very best steel you can use" -Dwayne Dwyer.
If I was in the military and had to go out to the sandbox, that's the steel I would want.
Both Mick and Dwayne use CPM-3V as their "user" steel.
The only steel I like as much is ELMAX.
 
I look forward to learning more about 3V. I only know what I have learned from some friends that make competition knives and they suggest that it really depends on what and how you cut when selecting a steel.

I.e. sword vs chopper vs slicer vs folder.
 
Welcome Prometheus. Filling out your profile will be helpful to you and to us.

CPM3V is a bit of a challenge for a first knife unless you have equipment for working it. For a first hand made knife, may I suggest 1084 for carbon steel, or CPM-154 for stainless steel.


Sorry to divert the thread, guys. Now, back to our regularly scheduled 3V chat.
 
Not to sound arrogant or Ignorant, but how hard can it be to shape some steel.?... I work for a company that will allow me to borrow any tools. I E (Grinder, jigsaw, bandsaw) that I need, and my patience I must say, is very strong.
 
Oh yeah, I will send my blade to a custom heat treater it, so. Isn't The only thing I have to worry about is removal?since cpm 3v does not require forging because it already has a very fine grain due to the Crucible particle metallurgy :)
