The 10Good #8000 grit sharpening stone is an ultra-fine polishing stone designed for those who want to push their edges to the highest level of refinement possible. Made in Japan using advanced resin-bonded diamond and CBN (Cubic Boron Nitride) abrasives, it delivers exceptional smoothness, precision, and edge clarity on high-performance kitchen knives.

The #8000 grit is especially impressive on carbon steel knives, where it produces an incredibly refined and highly polished edge with a silky, effortless cutting feel. While most stainless steel knives will rarely require this level of refinement, the #8000 excels as the ultimate finishing step for enthusiasts seeking maximum sharpness, edge smoothness, and visual polish on premium carbon steels.

Unlike softer traditional ultra-fine stones, the 10Good #8000 maintains excellent flatness, consistency, and controlled feedback with minimal dishing and wear. The resin-bonded construction allows for precise refinement without the overly muddy or fragile feel often associated with extremely high grit polishing stones.

For sharpeners looking to achieve the highest level of edge refinement and finishing performance, the 10Good #8000 delivers extreme polish, precision, and control in a premium Japanese-made package.
