Spyderco was founded in 1976 by Sal and Gail Glesser.

In 1978, they settled in Golden, Colorado, and initially, the company focused on selling our first product: the Tri-Angle 

Sharpmaker™ which was primarily sold at fairs and trade shows around the country. 

 In 1981, Spyderco introduced their first folding knife, the C01 Worker.

That knife pioneered the concept of a round hole in the blade
for one-handed opening, a clip on the handle for carrying 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.
