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° (15° each side) or 40° (20° 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 brass 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.
Spyderco was founded in 1976 by Sal and Gail Glesser.
Initially, the company focused on selling our first product
—the Tri-Angle Sharpmaker™—primarily at
fairs and trade shows around the country.
In 1981, the Glessers put down roots in Golden, Colorado and introduced the first Spyderco folding knife. That knife pioneered the concept of a round hole in the blade for one-handed opening, a clip on the handle for carry at the top of the pocket, and the option of a serrated edge for aggressive cutting performance. Those features revolutionized the knife industry and literally defined the form of the modern folding knife.
Since then, Spyderco has steadily grown to become one of the leaders in the cutlery industry. In addition to a worldwide distribution network and manufacturing resources in the U.S., Japan, Taiwan, Italy, and China, our innovation has also earned us an impressive portfolio of patents, trademarks, and industry awards. More importantly, it has allowed us to earn the trust and loyalty of countless thousands of dedicated knife users around the world—an audience to whom we are extremely grateful.
