Of course it's a mad idea because this great steeel doesn't need it at all but has someone tried to figure out an hamon on this steel?

just curious, it should be possible!

Did you mean cpm 3v or cpm s30v? The cpm s-steels are stainless. Cpm 3v is a non-stainless, hence no s.
I am not sure you would get much in the way of a visible hamon with either of these.
 
I'm not familiar with S3V, but I am a little more familiar with CPM3V and CPMS30V, both of which are air hardening steels. In my mind it wouldn't be possilbe to create a hamon on a similar steel.

Ron Duncan posted pics on BF several years ago, of a
CPM S30V blade with a hamon.

sorry if its sounds rude but i would like to see that cause short of clamping massive steel plates to the spine or not doing a propper HT on the steel i see no other way

like maybe if you oil edge quenched from 1600 after a complete real HT to 2000f might you get some thingk but i sure would be unsure of how the edge holding would be
 
" it's a mad idea " You're absolutely right !!! Both CPM 3V and CPM S30V are very fine steels but couldn't be improved with a hamon or even possible to get one.
 
Just asking!
:D

As I said before I know well that 3V is a fine steel.
It was a night idea, something mad, just some strange thoughts because after I seen a knife made with a SanMai of stainless steel and Carbon Steel I'm gettin crazy

Cheers guys thanks to all!

always keep thinking but make sure to temper thoughts jsut liek you need to temper steel :)

sanmai is good stuff if you are getting the property's that you want (SS clad for rust resistance ) or the core steel is so much $$ that you want to use as little as you can
:thumbup:
 
I've also seen a couple of photos of a temperline (not a proper hamon) in an air hardenning steel, s30v I think. It was made by keeping the lower 1/3 to 1/2 of the blade submersed in running tap water in a pan on a depth regulator plate while heating the spine with a torch. The blade was then etched and showed a fairly faint and cloudy, but visible, difference between the two areas. No mention was made of how the treatment affected performance as the experiment was done just to see if it could be done, as I recall.

You could do a san-mai of stainless on a 3V core though.... ;)

I know that Phil Hartsfield was able to put a hamon on A-2 and that is an air hardening steel.
