#2155   ON HOLD

Tenjyou suita from one of the close-in Honyama mines of Umegahata valley, this stone has a distinct patch of yellow namazu and is chock full of a nashiji pattern of tiny to medium size pear skin spots. There is a sparce and uniquely fine "su" pattern of ancient gas voids.

This is a razor hone hiding in a tool or knife size format. I did just today shave with a Henckels Friodur #451 honed on this stone and the HHT results were 5+ with the hair held ant 3/4 an inch, and the shave was single pass smooth and close. Effortless.

I have also tuned up a hand forged blue steel Japanese Deba on this stone as you can see in the photo. First with just clear water, great cutting action, then with a tomonagura slurry, fast to faster leaving an excellent contrast between the hard steel and soft iron.


From the Air Raid Shelter hoard, all of these stones possess hand sawn sides and ends with hand shaped backs, markers of pre-Taisho and likely Meiji Era working practices. These stones are a touch softer than the middle 20th Century diggings. Easy and a Joy to use, guaranteed.

All of my stones, even the smallest or least expensive come with a tested tomonagura, and a money back guarantee minus the return shipping.
