The Cold Steel Espada was inspired by the classical Navaja knives of Spain, but was utterly modern in both appearance and materials. A design collaboration between custom knife maker Andrew Demko and Cold Steel President Lynn C. Thompson. The Espada's blades are made from premium American S35VN Alloy Steel, chosen for its ability to not only take a super-fine cutting edge. They feature expertly polished G-10 scales and mirror polished 7075 Aluminum bolsters and frame. Each Espada is equipped with our patented Tri-Ad locking mechanism, proven to have shock resistance and strength.
