About This DUAL-GRIT DESIGN - Features a sapphire ceramic blend on one side (400 grit) for a fine, mirror-like finish and a coarser grey side (240 grit) for quick removal of file marks. VERSATILE SHARPENING - Perfect for field sharpening axes, machetes, and other tools, ensuring a keen edge with minimal effort. WATER-ABSORBING - The puck readily absorbs and retains water, creating a thin film on the surface to keep the pores free of metal fines for smooth sharpening. FAST CUTTING, FINE FINISH - Cuts quickly to remove material while leaving a fine, smooth finish that easily shaves and enhances tool performance.
