Spyderco Tri-Angle Sharpmaker with Safety Rods, Instructional DVD, Two Premium Alumina Ceramic Stone Sets for Blade Repair and Professional-Grade Finishing - 204MF

The Tri-Angle Sharpmaker (204MF) includes two sets of high alumina ceramic stones, a pair of medium-grit 7 by .5 inch stones for aggressive sharpening and a set of fine white 7 by .5 inch 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 to protecting your hands while sharpening. All components snap into the self-contained ABS plastic base and lid and are ready to travel with you. Die-cut into the base are keyed slots and holes fitted for the stones, which accurately set the stone's sharpening angle at for knives and a scissor setting.

Turn the base over, a channel lets you lay two stones side-by-side (flat-side up) for use as a benchstone. 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, so Spyderco advises you to 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. The sharpening system comes with instruction book and DVD and is autoclave safe.

Chances are you've heard it said, "a sharp knife is safer than a dull one." Spyderco believes this quote originated from first hand experience and find it to be true. The Sharpmaker was Spyderco's first product, which the company made and sold before getting into the knife business.
