Gokumyo Sharpening Stones are used for sharpening knives on Hapstone and Edge Pro knife sharpeners. All Gokumyo stones are 5-6 mm thick, 20-22 mm wide, and are mounted on high-quality aluminum blanks.

Gokumyo is the high-end line of sharpening stones by Suehiro. Gokumyo stones are universal and can be used to sharpen knives of any steel including high carbon, vanadium, and chromium steels.

Gokumyo is preliminarily lapped and does not require lapping after purchase.

Gokumyo should be used with water as a lubricant. Do not soak Gokumyo stones in water. Just splash, or use a water spray. Never store Gokumyo stones in water. Never dry Gokumyo stones near heat.

Designed to mimic the finest natural stones in performance and feel, Gokumyo 20000 is the finest of the Gokumyo series and is designed to provide the finest, sharpest edge without excessive trouble or frustration and for an extremely long time. Exceptionally hard and with low water permeability, this stone does not require soaking before use but will absorb water over time, yet is unaffected by prolonged water exposure due to it's composition, method of manufacture and high density.
