INTERPRETATION OF THE STONE

"This Ohira has an exceptionally clean feeling across the entire stone producing a rich dark grey mud. A medium soft stone with excellent feedback and ease of use, perfect for kitchen knife polishing where a thick matte Kasumi finish is desired. 

Tested on sanmai carbon clad white 1, blue 1,
White 1 Honyaki and wrought iron, I felt it performed best in Samani, but due to its fine consistency and soft texture it worked well to smooth over and blend areas of hamaguri and blending surfaces from flat to convex that harder stones may leave streaks or stepping. 

I often start stones with a surface texture from a worn #600 Atoma, but this stone I felt the surface texture needed to be finer to pull out the most of this stone, therefore I prepared the surface texture with a botan Nagura (or any similar grit range natural stone) using a medium amount of water

A very easy and enjoyable stone to use, suitable for experienced users as well as those wanting an easy and forgiving first natural stone."

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.
