This natural Japanese sharpening stone has a grit of approximately 7000. This type of stone is literally mined in Japan. Indeed, Japanese geology offers small treasures in terms of sharpening stones. It is new and imported directly from Japan; this type of stone is difficult to find in Europe.

This "Koppa," which means cut, comes from the "Nakayama" mountains, highly renowned for their natural stones.

It is a finishing stone that is hard enough to obtain an excellent polish on your edges, whether for tools or kitchen knives. It is an intermediate quality stone. The finish is well-polished; it is the right grit size to achieve a razor edge. It is equivalent to a 7000 grit. This one creates an extra-fine slurry. It will be very interesting for your carbon steel tools and particularly for your knives or Kanna blades in kamaji (recycled forged steel). It will reveal all the details of your "jigane" (base steel).

The stone measures 130 x 70 x 15mm and weighs 435g. It is a fairly fine stone with a uniform thickness. A beautiful koppa for your Japanese tools!

I tried it; it creates a fine slurry and leaves a magnificent polish. It does not have that scratching effect that sticks to the stone, which is very undesirable. I recommend using a diamond plate to maintain the flatness of your stone's surface.

It is a water stone, so you must wet it (using a spray). After use, let it dry naturally (avoid placing it in the sun). You must use a diamond plate to maintain the flatness of your stone's surface. It is preferable to glue it (epoxy resin) onto a wooden base.

With this tool, you will be able to discover Japanese tools. For cabinetmakers, sculptors, carpenters, cooks, or simply DIY enthusiasts.
