Takashima Koppa #1 Natural Polishing Stone #10,000 - #20,000

Quarried in Kyoto, Japan, these natural stones are rare and quantities are limited. Ideal for putting an extremely polished or refined edge on your knife, these are a must have for any serious sharpener or collector. As a natural stone, grits are impossible to measure accurately, but range between 10,000 and 20,000. The Takashima Koppas are on the smaller side but will still produce the same polished edge as a larger natural stone. These are a great value for anyone looking to experience a natural stone at a reasonable price point.
