Spyderco Four Stone Tri-Angle Sharpmaker Set Medium and Fine Grit Storage Box and Instruction Video – 204MF

The Tri-Angle Sharpmaker (204MF) includes two sets of high alumina ceramic stones: A pair of medium-grit (brown) stones for aggressive sharpening and a set of fine (white) stones for professional-grade finishing. The stones are triangular for sharpening Plainedges on the flat sides and SpyderEdges (serrations) on the corners. A furrow running the length of each stone lets you sharpen pointed items like fishhooks, darts, and awls. Included is a set of brass safety rods protecting the user’s hands while sharpening. All components snap into the self-contained ABS plastic base and lid, ready to travel with you. Die-cut into the base are keyed slots and holes fitted for the stones. They accurately set the stone’s sharpening angle at a 30 degree (15 degrees each side) or 40 degrees (20 degrees each side) for knives and a 12.5-degree scissor setting. Turn the base over, a channel lets you lay two stones side by side (flat side up) for use as a bench stone. The lid snaps halfway over the base creating a handhold for stability while you’re sharpening. Included is a set of brass safety rods to protect the users’ hands while sharpening. Ceramic stones, like glass, will break if dropped, handle carefully. Use them dry, without oil, water or lubricants. To clean: scrub stones with a plastic scouring pad and powered abrasive cleaner, let air dry. It is also autoclaved safe. The system comes with an instruction book and DVD.
