Spyderco
Golden, Colorado, 1976 — invented the round opening hole and the pocket clip, and publishes the country of origin on the product page instead of hiding behind an American address.
Sal and Gail Glesser founded Spyderco in 1976 and settled in Golden, Colorado in 1978; the C01 Worker of 1981 introduced three things that are now simply what a folding knife is — the round opening hole, the pocket clip, and a serrated-edge option. The round hole remains a Spyderco trademark. What earns the brand a page here beyond its designs is the disclosure: Spyderco states outright that it has manufacturing resources in five countries and identifies country of origin at model level, which is the opposite of the origin silence that runs through much of this roster.

What we'd reach for
- Para Military 2The compression-lock folder that most enthusiasts would name first, and the model the brand's own retrospectives center on.
- Delica and EnduraThe Japanese-made pair that has been in the line for decades and taught more people what a Spyderco is than anything else.
- Salt seriesCorrosion-resistant steels aimed at saltwater use — the line that matters if the knife lives on a boat rather than in a pocket.
- Tri-Angle SharpmakerThe sharpening system, and arguably the most-recommended maintenance tool in the whole knife world.
- byrdThe value line, with its own mark — a comma-shaped hole, not the round one.
- Mule TeamBare-blade runs in varying steels, sold for people who want to test steel rather than buy a finished knife.
