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.
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.
Spyderco knives are respected for their simplicity, reliability, good ergonomics and functional aesthetics.
They are popular with many markets including private citizens, fire and rescue personnel and law enforcement officers.
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.
