Loyd, The way I temper my hawks is with a torch. I heat till non magnetic and quench in trans fluid preheated to 130 to 140 degrees. I don't do a long soak time after reaching non maganetic because I use mostly simple carbon steels (10XX). I draw the cutting edge back to blue with the same torch and the hammer poll back to straw. The spikes I do not temper. I always normalize 3 times before quenching. I have done a couple hundred hawks this way over the years and have not had any problems.
