Buy 🧨 #679 Imanishi Ohira Tomae Type 40 Size 1192 Hard Fast Grams 4 Hardness 4.5+ Fineness 🎁

Old stock stone from the Tomae strata of the Ohira mine. A hard fast cutting stone that creates a fine mirror finish with some good contrast between jigane and hagane. An excellent hard stone that is almost too hard for knives but not. That said this stone might not get along with steels with large carbides, expect scratchy-ness on busy alloys or less refined heat treatments. 

Nice and flat with square sides, no visible seams, has pockets of su visible on sides, none on surface.  

Ohira:

A ‘Nishi-Mono’ or Western mine that produces some of the highest quality whetstones. This mine is most popular for producing Uchigumori, which is a famous stone type used for sword polishing. For knife users however, we love Ohira Uchigumori to produce a dark jigane and frosty hagane. Ohira mine also produces highly sought after Suita and Tomae stones of various hardness, typically having a fast cutting speed and a toothy yet refined edge.

This stone has not been lacquered on the sides which is recommended to avoid splitting along bedding planes. Do not soak. We do our best to disclose any cracks or flaws but being a naturally occurring stone we cannot guarantee against these. That said these have been selected by an experienced stone dealer in Kyoto with decades of experience.
