When I heat treated the blade that I just made I heated to 1500º F. and soaked it for about 5 minutes after the oven returned to heat, and quenched in a slow quench oil from McMaster-Carr. The blade is single bevel, flat on one side. After quenching the blade took on a gentle curve over the whole length away from the side with the bevel. The thickest point on the spine is 3/32" thick.
My next blade is going to be ground on both sides, so am I likely to see a repeat of this warp in some way? Was the warp a result of insufficient soak time in the oven? And is there any way to correct this.
As it is, I don't see this as a problem for the things that I want this knife to do, I think that the curve might help when sliding down the side of a chicken carcass, for instance, butt I will know better when I get around to boning the body of the chicken that I roasted last night.
Any insight or help would be very much appreciated!
