    Vendor Description

    Umajiyama production Layer is Ogami Slightly hard finishing whetstone.

    • A whetstone produced in Umajiyama, slightly hard but easy to handle. 
    • Umajiyama's whetstone is hard, but it is soft and easy to spit mud, which is rare in Nishimono. 
    • The amount of mud that does not spit out too much is exquisite, and the blade is finished smoothly. 
    • It is versatile enough to finish even from 3000 artificial, but if it is difficult to handle, please use Nagura or Diamond. 
    • It will be easier to sharpen if you put a thick towel on it, but it will be easier if you stick it on the board. 
    • Since it is well cured to the back side, it is easy to remove.

    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.
