Okudo Tomae Iromono Koppa Japanese Natural Toishi Finishing Whetstone

This exceptional Japanese whetstone was selected and purchased by us directly from Japan, then thoroughly tested and coated with cashew lacquer on sides and back to protect the stone for long term use.

It measures 130 mm long (5.12 in) × 50 mm wide (1.97 in) × 20 mm tall (0.79 in), and weighs 283 g (0.62 lbs).

Hardness: 3.4
Nicely shaped Softer Tomae stone from The Okudo mine. This stone has some rather interesting visual characteristics. First it has a vibrant Kiita yellow base with red Iromono blush spots and lighter yellow Namazu or catfish patterns. The surface has a few lines but upon testing them, none of these lines scratched or affected the edge. This stone is fine enough to finish a straight razor of Kamisori with light pressure and proper water/slurry viscosity. The mud must be kept thin with a high percentage of water to yield the finest edge possible. The stone is very grit rich and fast cutting which is a rare trait for a softer stone. This makes it a great option for knife polishing and edge sharpening. it also means that this stone is fast cutting enough to remove medium grit scratches with ease.
