(Stick your blade into the sand.) You may notice that I prefer to differential temper for plain HC steels. The high alloy blades get sent to a pro! I will sometimes use an oven for snap tempering. (Tempering to a lower temp to make sure a freshly quenched blade doesn't self destruct waiting for the full tempering cycles.)
