A dual grit ceramic puck stone in our acclaimed Arctic Fox sapphire ceramic blend on one face with a coarser grey face for a one-two punch when field sharpening axes, machetes, and other tools. The grey medium face will rapidly erase scratch marks from a file, while the icy blue fine side will bring the edge to a hazy mirror finish that easily shaves. Readily absorbs and retains water, with a thin film on the surface to keep the pores of the stone free of metal fines. Cuts quickly, yet leaves a fine finish.
The only thing wrong with these examples is the very edge of the stone has some of the coarse grit smudged up into the fine. The smudge is very shallow and will not meaningfully impact effectiveness--purely cosmetic.
