Ohira Uchigumori hone
From the Tenjou Strata (layer) of Ohira mine. Uchigumori is a fantastic for honing razors swords and Chef knives. It's unique particle properties allow it to do multiple things synthetic stones cannot, and one is to instill the perfect kasumi finish in blades of 2 different steel types or tempers. This piece is perfect for both Chef Knives and razors. You can hone directly on it or use as finger stones to develop that hazy finish of a well polished and honed fine blade. A Kasumi finish is shown in the last picture on the end of a Yanagi sushi knife. Note the dark hazy contrast to mirro finish of the edge
This is a partially flattened hone of Uchigumori which is very clean and a beautiful purple grey, with natural pink momiji patterning (momiji is Maple leaf, as this type of pattern resembles Japanese Maple leaves). there is a slight side dishing from honing knives on it of about only 2mm in depth (visible in second picture) that you may want to flatten with a lapping plate before honing straight edge razors on, though you can work around it as well, as I do. I will flatten this stone upon request before shipping if you just include a note with your wish with your order or send an email to our gmail address.
This piece is very clean and consistent.
