INTERPRETATION OF THE STONE

This Ohira is a perfect stone for those wanting to get into polishing with natural stones. A medium soft stone that’s not to muddy or sticky but has excellent feedback and high ease of use.

In the 4k-6k range this stone can be a pre finisher or finishing stone. A very forgiving stone that can take a lot of pressure applied for removing lower grit scratches in the 2-3k range but fine enough that with some finesse can produce a fine Kasumi finish.

Suitable for both polishing and edge sharpening this is an all around great stone for every user level

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.
