This knife began life as a mistake, with a big notch (from a bolt-hole and pan-head countersink) in the cutting edge. So, it was re-ground to become what you see here.
This is the first example you’ve seen here, of knives made from a 4-foot taper-ground circle saw blade that I acquired. Thickness is about 1/4 inch. The steel has not found its way to the lab yet, but it is possibly L-6. I did re-heat-treat it by the usual normalize-anneal-straighten-harden-temper sequence. Overall length is 12 inches, 7 inch blade. The knife weighs 12 ounces, sheath 6.5 ounces. $375.
