Mizukihara Uchigumori Jito Koppa Japanese Natural Toishi Whetstone

This exceptional Japanese whetstone was selected and purchased by us directly from Japan, then thoroughly tested. 

It measures 155 mm long (6.10 in) × 55 mm wide (2.17 in) × 27 mm tall (1.06 in), and weighs 516 g (1.14 lbs).

 This beautiful Renge packed Uchigumori is firm, dense, fast and fine. Its final polish straddles the line between Hato/Jito. It is a very inky and fast cutting stone which smells strongly of iron when sharpening. Water only honing is exceptionally smooth. The stone releases black swarf with water only showing a glimpse of its cutting abilities. When slurried, the stone acts much more fast cutting and the beautiful pink slurry is velvety. This pink slurry is quickly darkened with the grit rich nature of this stone. A razor can be honed to finish quite easily with slurry management and pressure management being key factors. For knife polishing, this excells in all categories. Fast cutting abilities and a brighter polish make this stone a bit different than normal softer Hato Uchigumori.
