Founded in 1979 by Sal Glesser, Spyderco is a brand of knives and cutlery manufactured in America, Asia, and Europe, and distributed in more than 60 countries. Two years after its inception, this family business moved to Boulder, Colorado, where its main headquarters remain today.
The key innovation of the Spyderco knife was being the first to feature a round hole in the blade for one-handed opening, a pocket clip for easy carry, and the option of a serrated edge for more powerful cutting.
Spyderco continues to drive innovation in cutlery and to maintain the trust of customers who rely on its durable knives, made from quality materials and designed for easy, comfortable use that solves any problem.
Why do Spyderco knives have a round hole in the blade? It’s a common question, and the answer is simple. In their 1981 patent, Spyderco broke the mold by introducing a revolutionary way to open a knife with one hand: sliding your thumb through the hole, safely and quickly, with no risk of cutting yourself.
This hole has become a true symbol of the brand—a mark that lets you know you’re holding a Spyderco knife or pocket knife.
Distinguished by the manufacture of high-end knives and pocket knives, and with a philosophy based on continuous quality improvement, Spyderco offers more than 300 cutlery designs and holds over 100 registered patents. Its capacity for innovation and product reliability has made Spyderco a benchmark in the world of the oldest tool known to man.
