A dual grit pocket 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 knives and other tools. The grey medium face will rapidly repair minor nicks, rolls, or blunting, 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 some minor intrusion of the medium grit into the fine grit side. Not to such a degree as to cause a meaningful difference in use!
