Use existing/other stones in the Nano Hone System
Stones have the same dimensions: 210 mm x 75 mm x 10 mm. So, why buy new if you already have a few. Or, just use your prefered stones for the specific work you need to do but do it in the Nano Hone System.
These plates and stickers make it easy. Stick and sharpen.
