Thanks Norm,
The light brown sheath is for ths smaller karda from a YCS, the darker one is for the larger. The black sheath actually fits both of my 9" YCS kardas.
Heat treating O-1 is pretty easy. We'll have to wait for performance reports from Leatherface to see if heat treating it WELL is easy.
Hope I got it right.
All you do is heat it with an oxy-acetylene torch til a magnet doesn't stick to it, then edge quench in 125 degree oil. Grind off the scale, and temper twice in the oven at 400 degrees for an hour.
