The Naniwa EBI #3000 diamond stone is a professional sharpening stone designed for intermediate finishing of knives, chisels, Japanese planes, and other cutting tools. Its #3000 grit refines the edge with precision after shaping, effectively preparing the blade for a very high-finish polish.

Its 1mm sintered diamond surface offers excellent wear resistance, consistent abrasion, and constant performance, even on high-hardness Japanese steels and modern alloys. Usable simply with water, without soaking, it comes with a dressing stone to maintain a perfectly performing surface.
