Spyderco Tri-Angle Sharpmaker with Instructional DVD Model 204MF

The key to sharpening any cutting tool is removing the steel at the edge while maintaining a consistent angle between the blade and the stone. Spyderco’s Tri-Angle Sharpmaker takes the mystery out of this 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.
