The EBI #800 diamond stone is a professional sharpening stone manufactured by Naniwa Abrasive Manufacturing , a renowned Japanese specialist in the field of sharpening.

With its #800 grit, it allows for more precise edge shaping while remaining aggressive enough to correct angles and refine a blade already prepared on a coarser grit. It provides an excellent intermediate step before moving on to finer stones.

Its ultra-hard diamond abrasive allows for efficient work on all types of steel, including hard steels and difficult materials. The 1 mm diamond layer is integrated using a sintering process, ensuring excellent durability and significantly reducing the risk of delamination. The cut remains consistent and even after prolonged use.

The stone is used simply by wetting its surface with water. Soaking is not necessary. It comes with a buffing stone to maintain the surface and preserve its performance over time.
