Kunsuto Sharpening Stone Series

This stone series was developed in collaboration with sharpening stone experts. The aim was to create a Japanese series suitable for both high-alloy and low-alloy carbon tool steels. The extensive tests were accompanied by macro- and micro-images of the individual blade shapes. The stone series has a medium-hard bond that does not lose its sharpening ability even when coarse-grained binding components (including chromium and vanadium) are present in the tool steel. Nevertheless, good material removal and a pleasant sharpening were observed for both steel types. The macro- and micro-images showed a harmonious surface and a precise blade shape for both steel types.

Before use, the stones should be soaked in water for at least 10 minutes, but they should not be kept in water constantly.
