The Konosuke HD2 is one of the iconic knives on our site. Known as a "laser" these knives are thin and cut exceedingly well.
The blade is a mono-steel construction using HD2, semi-stainless steel. The heat treatment on the blade is in the range of 61 HRC. As mentioned the grinds and geometry on this knife are designed for high performance, and boy does it deliver! This knife is not only thin at the spine, but it is insanely thin behind the edge. Couple the thinness of the blade with the steel's ability to take and hold a rather acute sharpening angle, and you are in for a real treat!
The handle is their very nice, ho wood octagonal with buffalo horn ferrule.
