Diamond Sharpening Stone 150mm Extra Fine for Knives & Chisels

A 6in 150mm diamond sharpening stone with an extra fine grade surface, used for refining and finishing cutting edges rather than reshaping them. It is suited to precision edge work where a tool already has its profile and just needs a cleaner, finer finish.

Used for regular maintenance of precision cutting tools, this stone suits workshop use, trade benches, toolboxes and careful jobs at home. When working on tools that need a keen, clean edge for accurate cutting, the extra fine surface helps with touch-ups and final sharpening stages. It is a sensible option for anyone carrying out routine tool care without wanting a complicated setup.

This 6in sharpening stone is easy to keep on a bench or store in a toolbox for repeated use. Diamond stones like this are built around a durable abrasive surface and are used with water, which keeps preparation simple and avoids the need for separate lubrication. The extra fine grade is aimed at precision edge refinement rather than heavy stock removal, so it is better suited to finishing work and maintaining already serviceable edges. For regular sharpening touch-ups, that makes it a useful stone to keep close to hand.
