The original Spanish navaja, like the one pictured here, can possibly be considered one of the world’s first defensive folding knives. It was such a credible defensive (and offensive) weapon that carrying one was a capital offense under Napoleanic occupation.
Little wonder that designer Ed Schemmp chose it as the inspiration for his Spyderco Navaja, which he discusses in the short video below.
The $150 Navaja, with its ratchet-opening S30V blade, is fairly uncommon. It looks a bit unwieldy for an EDC, but I could be wrong about that. I’m really curious how that unusual blade profile performs at routine cutting tasks, and looking for a T&E sample to find out.
