Few companies can claim to have redefined an entire industry. Spyderco is one of them. Founded by Sal and Gail Glesser in 1976 and headquartered in Golden, Colorado, Spyderco introduced innovations that shaped the modern folding knife—features so fundamental it's difficult to imagine EDC without them.
In 1981, Spyderco released the C01 Worker, introducing three industry-changing elements: the Trademark Round Hole for one-handed opening, the pocket clip for convenient carry, and a serrated edge option. Before Spyderco, pocket knives lived at the bottom of your pocket and required two hands to open. The Round Hole changed that—allowing fast, ambidextrous deployment with a simple thumb roll or the now-famous Spydie Flick. The pocket clip repositioned the knife for immediate access, a feature now standard across the industry. These innovations earned Sal Glesser induction into the Blade Magazine Cutlery Hall of Fame in 2000.
Engineering That Performs
Spyderco designs prioritize ergonomics, cutting geometry, and materials over visual polish. Full-flat grinds slice efficiently, textured G-10 and FRN handles provide secure grip in demanding conditions, and finger choils offer precision control for detailed tasks. The Compression Lock—found on the Paramilitary 2, Para 3, and Shaman—provides exceptional lock strength while allowing safe, one-handed closing without placing fingers in the blade path.
Blade Steel Innovation
Spyderco has pushed blade steel boundaries for four decades. They were among the first to bring powder metallurgy steels to production knives, introducing CPM-S30V and later S90V, Maxamet, and ZDP-189 to mainstream users. Their Salt series pioneered H-1 and LC200N for rust-proof marine performance. In 2020, Spyderco partnered with Crucible Industries to develop CPM-SPY27—a proprietary steel exclusive to Spyderco that balances edge retention, corrosion resistance, and toughness across American-made models including the Paramilitary 2, Para 3, Native 5, Manix 2, and Shaman.
Iconic Models
The Paramilitary 2 distills the performance of Spyderco's full-size Military into a compact, everyday-friendly package—one of the most popular folding knives ever produced. The Para 3 scales that formula down for those who prefer a shorter blade. The Shaman offers a larger, more robust option for harder use. The Native series delivers American-made quality in a traditional lockback format. The Manix 2 provides exceptional grip security with its ball-bearing lock. The Delica and Endura remain lightweight, affordable staples in an ever-expanding range of configurations.
Sprint runs and dealer exclusives keep the catalog fresh for collectors, featuring unique steels and handle materials produced once and never repeated. DLT Trading regularly carries these limited variants alongside the full Spyderco lineup.
