Does anyone know of a maker using CMP-T440V? I'm looking for a fixed blade, full tang, micarta handled knife.

Phil Wilson, (seamountpcw@earthlink.net), makes fixed blades out of 420V and other CPM steels as well. Drop him an email.

I'd be a little leary of a large blade(>4") in 440V. Although it's edge holding and abrasion resistance it ledgenday, it's toughness isn't. For a large blade, maybe consider 420V(better toughness, but other specs are almost the same), 3v(indestructable), D2 or if you're insane, or CPM-D2(see about 10 days ago in REKAT's forum)--but only if you have sadistic tendencies towards makers(it's harder than h$%* to grind

Spyderco has said that 440V is not weaker than ATS-34 in the toughness department and there are a lot of people making big ATS-34 blades. Tom, you have been using ATS-34 for awhile, how does 440V compare to it?

Cliff, what Spyderco stated is true. Again, the charpy values prove this. Some people think that the ATS is not good for big blades either. I think as Tom as mentioned in the past, it's probably more to do in the way the heat treatment went than anything else. Doesn't Brend also use ATS-34(Besides D-2)? His knives are always at the top of the tough knife talk.
 
hate to disagree, but i have found 440v to be extemely brittle, even as compared to 440c, i read this in the first articles that came out on the stuff and it has been my conclusion that 440v is the greatest skinning knife steel around but dont stick it in a joint....on the other hand...and i will admit that i am very stubborn about some things....paul bos has been heat treating my steel from day one...and i have found ats34 to be one of the toughest steels i have ever used....i make small machetes out of it...3/16 stock...flat ground...and have pounded on concrete with no ill effect, although i dont grind my edges down to thin air like some...for a knife thats going to be used very hard i leave the edge (before sharpening) at around .025" ....i have only had two 440v knives come back with any problems...but one was a standard drop point, probably 3 1/2" long....and the guy tried to cut the head off a large animal that he shot....the blade looked like a saw when he brought it back...they werent large chips....lots of small ones....all i had to do was resharpen aggressively and it was fine, back to original looks...but it showed me something very significant...also...sent a folder blade to paul out of 440v that tweaked slightly in heat treat and when we tried to straighten it out...ever so gently, snap....in half right at the middle of the hole (see website for hole placement www.mayoknives.com so thats my experience....i have NEVER ever had a knife come back that was broken or even had the tip snapped off...but maybe im lucky...i also design my knives carefully for the intended use....thats one mans opinion...just made a knife out of 420v... am going to use it hard and see how it holds up..but when i make a knife out of 440v i always tell the person to be gentle with it..
