Spyderco was founded in 1976 by Sal and Gail Glesser. Initially, the company focused on selling their first product —the Tri-Angle Sharpmaker™—primarily at fairs and trade shows around the country.
Based in Colorado USA, in 1981 they introduced their first Spyderco folding knife. That knife pioneered the concept of a round hole in the blade, a clip on the handle for carry at the top of the pocket and the option of a serrated edge for cutting performance. These features revolutionised the knife industry and 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, their innovation has earned an impressive portfolio of patents, trademarks, and industry awards. More importantly, it has earned the trust and loyalty of countless thousands of dedicated knife users around the world
