The Ulna, is designed to be worn in the arm, but can be worn anywhere on the body. This knife is very sharp, lightweight and durable knife. The blade is constructed from Stainless Steel, with a hardness of 55-56HRC. The knife is low-profile and designed to be worn close to the body, eliminating “line traps” and minimizing drag. The “Ulna” is a minimalist blade, designed with the freediver in mind. Slim, strong and lightweight, the “Ulna” checks in at a mere 85 g (2.99 oz) and with a 7 cm (2.75″) blade length. This small knife is a beast!
