Spyderco has collaborated with 30 custom knife makers, athletes, and self-defense instructors for designs and innovated the usage of 20 different blade materials. The first product Spyderco produced was the Portable Hand in 1976, this "spider-shaped device", which gave the company its name, was a series of angles, ball joints and alligator clips that helped people such as jewelers and hobbyists to work with small parts.
Spyderco pioneered many features that are now common in folding knives, including the pocket clip, serrations, and the opening hole.
based cutlery company that produces knives and knife sharpeners.
Spyderco's Founder, Sal Glesser, and his wife Gail, converted an old bread delivery truck into a motor-home and traveled to shows.
For his many influences in tactical knife design (most notably the pocket clip, serrations, and opening hole) and many collaborations with custom knife makers, Spyderco's President, Sal Glesser, was inducted into the Blade Magazine Cutlery Hall of Fame at the 2000 Blade Show in Atlanta, Georgia.
The blade steel used by Spyderco over the years include: 52100, a ball bearing steel used in the first run of the Mule project.
Their most common handle material is FRN (Fiberglass Reinforced Nylon) and G10, although they make knives with steel handles as well as some limited editions with handles from various other materials.
Knives made with CPM S30V steel were previously all made in Golden, Colorado, USA, however Spyderco has recently begun shipping CPM-S30V to Taiwan to have knives produced there using this steel.
As they became more successful, they graduated from the bread truck to a truck and trailer. Spyderco began producing knife sharpeners in 1978 and produced their first folding knife, the C01 Worker, in 1981.
Most knives produced by Spyderco are folding knives of various designs, blade steels, handle materials, and locking mechanisms (including two patented proprietary locks); however, they have also produced fixed-blade knives for various purposes.
