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. Its durable ABS
plastic base contains keyed holes that accurately set the stones
sharpening angles at a 30 degrees (15 degrees each side) or 40 degrees (20 degrees each side)
for sharpening knives. 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. The Sharpmaker system includes two sets of high
alumina ceramic stones: a pair of medium-grit (brown) stones for
aggressive sharpening and a set of fine (white) stones for
professional-grade finishing. A set of aluminum safety rods protects
your hands while sharpening and all components snap into the
self-contained ABS plastic base and lid for easy storage. Every
Sharpmaker comes complete with a detailed instruction book and DVD
that guides you step by step through the process of sharpening
knives, scissors, awls, and many other tools.
