All of my knives are made by
the stock removal method. What this means is that I purchase 440C surgical stainless steel flat bar, cut it to shape, then
grind the bevel and cutting edge. The advantage of this method is that I can use a high quality tool steel which has very
The choice of 440C was because of its high chromium content (18%). This very
high chrome content makes the steel very resistant to staining in use. Recently I have included Stellite 6K in
my production line because it is virtually impervious to corrosion and has superior edge holding capability. The Stellite
6K will be used primarily for special "one of" designs.

After grinding the knives are sent to heat treating where they are heat treated
in an inert atmosphere oven , then frozen in a cryogenic chamber with liquid nitrogen and finally tempered to my preferred
working hardness (Rc 56-58). The heat treating and cryogenic treatment are carried out to convert the free carbon in the steel
to carbide centered crystals, carbides if you will, because these are very hard and wear resistant and greatly increase the
edge holding ability of any knife. The tempering is necessary because after the heat treating and cryogenic treatment the
blades are very hard (Rc 62-63) but they are also very brittle, the tempering is necessary to reduce this brittleness. I have
found that a hardness of Rc 56-58 nicely balances the need for good edge holding and almost eliminates the risk of blade breakage.
