INTERPRETATION OF THE STONE

This Atago Koppa was a very interesting find, both very fine with very strong cutting speed. 
Often I don’t find koppa of such high quality but this was an exception. 

Having a very smooth, fine, even cutting experience, sharpening both single bevel knives as well as Japanese woodworking tools was easy. 

I really liked this stone for edge sharpening both single and double bevel knives, the edge was was very fine but had a nice crispy feeling. 

Best set up using a 600 grit atoma to dress the surface washing of all mud, then using little water to start a very dark almost black slurry  created from pressure on the soft iron.

RECOMMENDED USE FOR :

Best suited for edge sharpening, strait razors, Japanese woodworking tools, kamisori and single bevel iron clad kitchen knives .

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.
