Japanese Crystal-Toishi (Whetstone) - #3000 (Brown)

Presenting an extensive selection of Japanese crystal-toishi (whetstones), thoughtfully curated to encompass varying abrasion levels (grit), and meticulously sourced from a distinguished Japanese establishment renowned for their expertise in kintsugi and maki-e art. These whetstones are highly specialized tools, ideally tailored for the precise polishing of urushi lacquer layers.

While using these whetstones, you have the option to employ our washi-tape or curved masking tape range, depending on your preference, to create a protective lined barrier along repaired contours, ensuring the safeguarding of ceramic finish and glaze. During the sanding process, just a few drops of water suffice. Employing wet sanding techniques effectively prevent surface scratches and contribute to a smooth, uniform finish, especially when transitioning to dry sanding.
