How do you temper on the curve?


Recommended Posts

Hey folks,
I have been itching to hammer out some khukri style blades, but I am worried about the heat treatment. I understand that the kamis who make them use water out of a kettle and pour it onto the hot blade...I guess they do this edge up? I would like to be able to heat the whole thing to critical temp and then harden the edge, and leave the back softer, but because of the curve of the spine I cannot do this, my tang would be as hard as the edge.:confused:
So how do you folks deal with curvy blades?
