#751 Maruoyama namazu shiki uchigumori namazu

Super size stone at 50mm thick I found that it is a perfect knife
stone that is grit rich and will hone up even the hardest steel
knives quickly and creating longer lasting edges. Although from the
Tenjyou layer of uchi-gumori and hachi-gumori, the shik-gumori layer
is the deepest and the hardest within that strata.  This is not a self
slurrying stone but with just clear water it will build a rich black swarf
from stainless or high carbon steel that will help to lubricate and
encourage advanced cutting powers. One end of the stone has pure
white namazu patches, these are also grit rich and do not feel any
different under the blade. The same with the non-toxic brown yaki
which does not scratch the steel in any way.

Can be used for tools, striking chisels as the final stone, for plane
blades as a middle stone or razors as a middle stone. You will be
surprised by the heft of the stone.

The stone (toishi) has been lapped perfectly flat and the corners and
edges beveled unless otherwise noted.  All of my stones come with a
tested and appropriately sized tomonaguara slurry stone, and a money
back guarantee minus the return shipping.
