Spyderco Tri-Angle Sharpmaker

'The Spyderco Tri-Angle Sharpmaker is notable for its simplicity—no prior experience is required, yet it delivers professional results. Sharpening is done in four cycles of twenty strokes per side: place the blade alternately at the top of the right and left triangular stones and pull it down with light pressure. Built-in angle guides of 12.5°, 30° and 40° further simplify setup. The synthetic base and protective hand guard ensure safe, blade-friendly sharpening. Scissors, axes, other tools and even serrated edges can be easily restored to a sharp edge. Supplied with two pairs of triangular ceramic stones in different grits, detailed instructions and a DVD.'
