Spyderco

Spyderco is more than a knife brand—it's a culture built on innovation, precision, and the pursuit of performance. Founded in 1976 by Sal and Gail Glesser, Spyderco began not as a knife company, but as a toolmaker. Its first product, the Tri-Angle Sharpmaker, laid the foundation for a design philosophy centered on function over form. By 1981, Spyderco changed the knife industry forever with the C01 Worker, the first folding knife to feature a pocket clip, a one-handed opening Round Hole, and a fully serrated edge. These features, now ubiquitous, were revolutionary at the time.

Spyderco’s philosophy is rooted in Continuous Quality Improvement (CQI)—an ongoing process of refining even the smallest details. This is why you’ll find steel types like CPM S30V, S110V, Maxamet, LC200N, and SPY27 (Spyderco’s proprietary steel developed with Crucible) used across their line. Every model is engineered with purpose, from compact slipjoints to overbuilt tactical folders and rust-proof dive knives.

Spyderco collaborates with an international roster of respected designers and users: military professionals, law enforcement, bushcraft instructors, and custom knifemakers like Bob Lum, Michael Janich, and Gayle Bradley. These collaborations bring a variety of philosophies into the Spyderco line, reflecting real-world needs and use cases.

Fan Culture & User Base

Spyderco has one of the most passionate and diverse fan bases in the knife world. Its users range from Everyday Carry (EDC) enthusiasts and outdoor adventurers, to first responders, tactical professionals, and even chefs who appreciate Spyderco's Japanese kitchen knife lines. Spyderco collectors are known for their loyalty and attention to detail—some owning hundreds of models and eagerly awaiting sprint runs, exclusive variants, and factory seconds sales.

The online community around Spyderco—particularly on forums like BladeForums and Reddit’s r/knives—is lively and well-informed. Fans often engage in deep discussions about edge geometry, lock design (from Compression Locks to Ball Bearing Locks), steel performance, and handle ergonomics.

Materials and Engineering

Spyderco knives are built with performance-first materials. Handle scales come in G-10, FRN (fiberglass-reinforced nylon), carbon fiber, Micarta, titanium, and stainless steel. Many blades are full flat ground for superior slicing geometry, and numerous models are offered in fully serrated (SpyderEdge) or plain edge formats.

The company's manufacturing spans five countries, each known for specific specialties:
