Fashioned from a single piece of 4mm thick Corrosion-free Titanium the Argonaut is born to take on anything you throw at it.

Nearly impervious to rust thanks to its titanium construction, the Argonaut blade is coated in black Electro Deposit Primer (EDP). This EDP further protects the blade from corrosion while itself being highly durable so the knife keeps looking like new even after years of tough dives.

The handle is double-wrapped in 5mm paracord to keep your hands comfortable, whether you're wearing gloves or going barehanded. The Blunt Tipped version of knife provides you with a safety net by preventing you from piercing your BCD or dive suit with the tip. Conveniently the tip is ideal for prying actions or for using as a screwdriver. The long serrated edge makes hacking through rope or tough fibrous material a breeze while the conventional knife-edge lets you make slicing cuts. The butt of the handle features a hardened tactical tip for hammering with the knife
