Cmp-3v?

[DennisStrickland]

phil wilson had worked with 3v sometime back & i believe he got good results for slicing knives at 61 or 62 but for choppers no higher than 58 or 59. do'nt know if he's doing any 3v now. he specalizes in high hardness fillet knives, but does some hunters.

I've been looking into this and a few other steels, I've got quench plates around, but still heat treat in the forge. Sounds like another reason to get an evenheat set up in the shop soon.

i love simple steels for some things
but i tell you its hard to beat 3v
im gettign ready to test a cpmM4 folder blade to see how it acts at rc63

i run my neckers and all other smaller 3v knives at 61-62
my chopper is 59-60 the problem is i am used to making kitchen knives adn razors (not an edge profile for a chopper ) so its tricky for me to grind a"thick" edge

from what I understand, you don't need a thick edge with 3V.

thicker then a kitchen knive or razor for sure 3V is a hell of a steel but when your are user to makeing blade that have a pre sharpened edge thicknes of .003 for razors to .007 for chefs (a hunter i would run .010 and a chopper much thicker )
but since i grind thin stuff i find it tricky to stop with the mass to add an edge to (on a chopper i would think .040 convexed in for max use )

BTW, I was finally able to get the edge on my 3V test knife to ripple(no chipping, but the edge deformed a little) when hacking and twisting it out of the wood. But, I had to grind it down as thin as a kitchen knife first.

Those Mathews boys know CPM3V as well as anyone and they came up with a very good way to quench their blades. The quench is extremely important because 3v is extremely quench sensitive and it is not unusual for first timers to come up with low hardness readings on 3V when first heat treating. Of course that Bradshaw guy and ol Hossom know a bit about 3V as well..........& don't get me started on Phil Wilson.
