This Daishi 800 is made of Hitachi Yasuki Steel which is the modern Hitachi metals version of Tamahagane steel derived from Japanese iron sand. It is one of the highest quality steels made in Japan due to its very high carbon content and extremely fine grain. Classically it would take a Japanese blacksmith days without sleep to produce a small amount of this treasured material. The purity of this steel allows for a very sharp edge that will hold its sharpness longer than other steels. The classic hollow grind blade provides and phenomenal shave! Be careful, Yasuki steel shaves so well it can become addictive. Blade Width: 20.3 mm or ~13/16"
HHT-0 - shave: The hair can be shaved immediately at the holding point. This is strictly spoken not a true HHT, but it does tell us that the edge is capable of shaving. [all other attempts must be made at least half an inch from the holding point]
HHT-1 - violin : The hair doesn't cut, but it "plays violin" with the edge. This is due to the shingles catching the edge, but it's not sharp enough to penetrate. On a full hollow razor, a faint ringing sound can be heard. On all razors it can be felt with the fingertips that hold the hair.
HHT-2 - split: When it is dragged across the edge, the edge catches the hair and splits it lengthwise.
HHT-3 - catch&pop: When it is dragged across the edge a bit, the edge catches the hair and pops it. The severed part will jump away.
HHT-4 - pop: The hair is popped immediately when it touches the edge. It still jumps away.
HHT-5 - silent slicer: The hair falls silently as soon as it touches the edge.
