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. Made with pride in the USA!
