Spyderco Tri-Angle Sharpmaker with Instructional DVD

The Spyderco’s Tri-Angle Sharpmaker takes the mystery out of the sharpening process and enables anyone to sharpen a knife effectively with just a few minutes’ practice. Simply keep the plane of your knife’s blade vertical and draw the edge along each stone to sharpen. It’s that simple. For serrated blades, use the rounded edges of the stones and a slightly looser grip to allow the stone to flow into the recesses of each serration.
