Glauca J1 Desert developed in cooperation with material experts from the Jagdkommando, a special unit of the Austrian Army. Durable medium-heavy folder with a dagger designed to maximize penetration, regardless of the intensity of wear.

N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with molybdenum 1.10% (Mo), vanadium 0.10% (V) and cobalt 1.50% (Co) for structural uniformity. Features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. Achieves a hardness of 57-60 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Blade - solid with a double-edged modified Tanto shape, provides above-average cutting and penetrating properties. The blade is coated with a non-reflective matte MIL-C-13924 BURNISHING coating. Combo partially serrated blade is derived with Full Flat grind which provides strength, excellent cutting edge geometry and extreme cutting performance of textiles, hard plastics, fibrous materials. Dual blade locking system: solid Liner-Lock mechanism supported by an additional locking mechanism. The steel double-sided hilt when the blade is folded, acting like a Flipper or like an Emerson hook, is complemented by a Thumb Stud, creating a triple quick-open system for the knife.

Handle - full-size with a length of 5", similar to assault knives. The anodized aluminum grip liners are finished with non-slip texturing to guarantee a secure grip. The so-called open-backed design simplifies cleaning and maintenance. A three-position clip allows you to carry the knife in tip-up / tip-down position with the tip down or up. The head of the folder is finished with a peg for breaking glass, on the back of the handle a system for safe cutting of belts or disposable handcuffs.

Sheath - made of Kydex plastic, equipped with a clip for mounting on the M.O.L.L.E. system. The holster allows you to carry the folder like a knife with a fixed blade. Allows the knife to be carried in an upright position on a belt or on a vest.
