Standard sharpening stones for classic systems like Apex, TSPROF, Ruixin, and so on, are 6 by 1 inches in size.
The set includes Boride CS-HD 150, 220, 320, 400, 600, 800, and 1200. Grit is according to FEPA.

The set also includes very high-quality powders for flattening the stones on glass.

In the photo, I placed the stones on the bags to show exactly which powders I recommend using to flatten them. The 320 and 400 stones can be flattened after you've already broken down the F80 powder with the F220 stone; that way, the grains become smaller and work more gently on the F320 and F400 stones.

The 600, 800, and 1200 stones can be lightly touched up (we're talking microns here) just on frosted glass with water.

The stones are flattened and ready to go. They work with water only, which is great because the sharpening area always stays clean, without any oily messes.

Reason for selling: switching to freehand sharpening.

The package will be packed with extreme care and common sense. All the stones will be individually wrapped, separated from one another by a thick layer of cushioning material.
