Riviera

Condition: hair moistened, tip out/root in

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.
