Spyderco Tri-Angle Sharpmaker #C204MF
The 204MF includes one pair of medium-grip (brown) triangle stones for aggresive sharpening, and one pair of fine-grit (white) triangle stones for professional-grade finishing. Their patented triangular shape sharpens plain edges on the flat sides and serrations on the corners. A groove running the stone's length sharpens pointed items such as fishhooks, darts, awls, and punches. Keyed slots/holes in the ABS plastic base precisely preset the stone's sharpening angle to a 30 degrees (15 degrees each side) or 40 degrees (20 degrees each side) for thick and thin profiled knife blades. On the end of the base is a 12.5 degree scissor setting. When turned over, the base's underside accommodates two side-by-side stones (flat side up) for benchstone sharpening. Plastic lid snaps halfway over the base creating a stable handhold and a pair of brass safety rods protect the user's hands during sharpening. Portable, all components fit into the base and the lid snaps on as a cover. Base can be bolted to a table or counter-top for permanent use. Instructional DVD (204DVD) and booklet included.
