INTERPRETATION OF THE STONE

This OZUKU was a real pleasure to use, extremely versatile for both polishing and edge work, with excellent feed back and ease of use. Very fast cutting speed that easily produced a black mud after a few passes.

A fine stone that has a feel and polish in the
8k + range, leaving a fine whitish grey Kasumi with a dark mirror finish on the steel. Tested on Hitachi white and blue steels both sanmai and Honyaki, as well as Tamahagane Honyaki and wrought iron cladding. Because of the very pure cutting feeling and fine grain of the stone a detail was easy to draw out of clad steel, Honyaki as well was very nice both on the soft and hard steel.

Edge sharpening on all the above steels was equally great, giving a good working edge but also capable of very fine polished bevels suitable for Sashimi or similar edge needs.

Started with a surface texture from a 600 Atoma and little water keeping the stone s bit dry in places produced the best results for polishing,

Recommend for experienced natural stone users.

Prepared for Use

Komon does more than simply select workable natural stones.
Even the finest natural stone cannot be used for sharpening straight from the mountain. Each stone must be carefully prepared and finished before it is ready for use.

At Komon, each stone is carefully prepared and finished by craftsmen with extensive experience and knowledge of natural stones, so that its qualities can be experienced from the moment it is put to use.

  • A STABLE BASE

    We carefully flatten the back side to ensure stability during sharpening. When additional support is needed, we attach a wooden base to create a secure foundation.

    Any wobbling of the stone affects the precision of the sharpening process; stability is particularly crucial during final polishing and edge sharpening.

  • A READY-TO-SHARPEN SURFACE

    The sharpening surface is flattened and prepared for use.
    Softer stones intended for polishing and finishing are given generously rounded edges. Harder stones used for edge sharpening are also carefully rounded to prevent the stone from damaging the blade.

    As a natural stone is used, new layers of stone will gradually appear. Regular flattening and maintenance are therefore essential to keep the stone performing at its best.

  • PROTECTING THE STONE FOR YEARS TO COME

    Natural stones are formed by nature, and some may contain weaknesses that could eventually develop into cracks.
    We identify these stones in advance and, when necessary, reinforce the surrounding areas with cashew resin to help prevent future damage.

    Cashew resin can scratch a blade. Before use, any exposed cashew resin on the corner should be carefully rounded with a medium grit diamond plate.
