INTERPRETATION OF THE STONE

This Ohira koppa is a very very easy stone to use, good cutting and polishing abilities producing its own mud naturally without aid of atoma or Nagura. 

The blade glides smoothly and easily over the stone regardless of steel or cladding type producing a beautiful even, fine matte Kasumi finish.  In the 4k-6k grit range, when used with a bit more water on the stone it produces a very good working edge. 

Overall a very enjoyable stone to use, perfect for those interested in a first natural stone or those who want a stone that gives an easy Kasumi with some fine detail.

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.
