Spyderco

Spyderco invented the round thumb hole and the pocket clip, and every one-handed folding knife since owes them something. The shapes look unusual because they follow the hand rather than tradition.

The Para Military 2 and Delica are the classics, and the steel selection is unusually adventurous — they will run a new alloy years before the rest of the industry. Ergonomics first, aesthetics second.
