    Mariner 2 – Heritage Series - The perfect EDC, born from legend.

    Born in the 1980s from the pioneering vision of Bob Terzuola, the Mariner was conceived as a true EDC to carry every day, without compromise. Today, this revamped version pays homage to the original, combining aesthetics faithful to the spirit of the first model with a modern, compact and legally compliant design under 3".

    The new Mariner 2 features a MagnaCut steel blade with a sheepsfoot profile, sharp, durable, and hardened to 64 HRC, set in a grade 5 titanium handle that guarantees strength without bulking up your pocket. Every detail has been carefully crafted: encapsulated ceramic bearings, steel liner lock with insert, 3D milled clip with the legendary dragon head logo, and a machined titanium thumb disc with dovetail joint.

    This reissue is not only a tribute to the history of custom design, but also a celebration of mechanical innovation and high-end materials, all precision-crafted in Dallas, Texas. A piece that combines past and future, for those who demand the best from a pocket knife.
