you won't melt the micarta. Micarta is tough and resilient and the heat on the blade will not affect the handles much. Busse is replacing but I would like to know what was done in polishing to so damage the blade. If they Rc'd the blade to 64, then someone heated it and quenched it in water to get that.
very interesting. I remember reading somewhere that in order to affect the heat treat of INFI you have to go over 900 degrees. If someone polishing a blade gets it that hot, they could not possibly touch it, and anyone doing that would be a maroon. Was there any response from the person that did the polishing? The Rc of 64 probably would not be the issue, but the ruining of the HT would.
I don't purport to be an expert on this subject, but two quick things:
First I'd be extremely surprised if you had to get to 900F to ruin the HT on a busse. Most are significantly lower than that, particularly low alloy steels, and even the extreme high heat steels only go as far as 1000F. http://www.crucible.com/eselector/prodbyapp/highspeed/cpm121.html Of course Nitrogen is screwball which leads me into my next point
Nitrogen is weird stuff. That nickel-nitrogen steel H1 is precipitation hardened and some amount of heat and mechanical force will harden it. Granted thats just a surface hardening, but thats where cracks form to propagate.
I'm not in the least bit saying I have even the foggiest idea I know what either happened here, or how to HT INFI, I'm just saying it'd really surprise me if you had to go as high as 900 to ruin the HT on a Busse. I mean that'd be fantastic news, yet another miracle performed by INFI, I just would be very surprised.![]()
As for INFI and temperature extremes, it is amazing. INFI is tempered at nearly 950 degrees. It does not begin to lose any significant hardness until it is held above 1050 degrees for a considerable amount of time. I have to believe that it would need to be extremely mishandled in order to do any noticeable damage.
Most of the simpler high carbon steels (of which INFI is NOT a member) can be drawn down in temper in a matter of seconds if the temperature hits above 500 - 800 degrees. Along the thin edge of a knife, a buffer or dremel can produce this level of heat and can cause serious damage if not executed by a professional. Always check the grade of steel and heat-treat specs. before assassinating it with the dremel tool Uncle Leo gave you for Christmas. Always keep the steel cool to the touch and you should be fine.
As far as INFI is concerned, care for and feed it like a friend. If the blade does get warm pour beer over it to cool it down. Stories out of Africa indicate that Beer Tempering only increases the performance of the steel. Is this true? I question nothing I hear from our friends in Africa.

Looks like someone stuck it in tree and then whacked/kicked it sideways to cause the lateral stress needed...
Quote from the Man, Busse him self: (from an old thread in 2000)
The look of the plunge line and the absence of INFI dimples on the ricasso and butt make me think machine.
In Soviet Russia, Birch chop Infi!
Difficult to say what exactly happened. It could have even been a lemon from the Busse Shop, and the sanding and polishing done may not have been the reason it broke. Obviously, the hardness and tempering was off, which is what caused the failure. Nobody's perfect. Faulty products happen. No need to make a conspiracy of it. The warranty is being honored, and that's what matters.

At all I don't know what to think.
Furthermore, do not try to polish a blade by using a buffing wheel!!! This damages the steel by causing localized heating which then alters its microcrystalline structure.
