This is a new, unused, parallel import product. The Tri-Angle Sharpmaker (204MF) includes two sets of high-alumina ceramic stones: medium (brown) stones for aggressive sharpening and fine (white) stones for professional finishing. The stones are triangular, allowing you to sharpen plain edges on the flat surfaces and spyder edges (serrations) on the corners. Each stone has grooves along its length for sharpening pointed items like fishhooks, darts, and awls. A set of brass safety rods is included to protect the user's hands while sharpening. All parts can be fitted into the ABS plastic base and lid. The base is engraved with grooves and holes for setting the stones. The sharpening angles can be precisely set to 30 degrees (15 degrees per side) for kitchen knives, 40 degrees (20 degrees per side) for hunting knives, and 12.5 degrees for scissors. Flipping the base over reveals grooves where the two stones can be placed side-by-side (flat surfaces facing up). The lid snaps onto the base halfway, creating a handhold for stability while sharpening. Brass safety rods are included to protect your hands while sharpening. Ceramic stones, like glass, will break if dropped. Use dry, without oil, water, or lubricants. Care instructions: Scrub the stones with a plastic scouring pad and a strong abrasive cleaner, then air dry. Autoclave is also possible. Includes foreign language instructions and a DVD.
