As the DH1-2 is a 154CM stainless steel, the electric heat treatment oven is used to accurately maintain the temperature for Austenitie-Martensite conversion.
I prepared the blade by placing it in a
stainless foil envelope which is type 304 0.002" I bought from McMaster
Carr. I cut it to 6" x 11" or so.
To consume any oxygen inside the
envelope, I placed some tissue paper. Each seam is folded and pressed
with a roller and then in the carpenter's vise.
the first time I have tried this technique, but from what advice I have
been given by several noted knifemakers I think this is the way to go.
The blade is now ready for polishing.
