This full titanium UltraLink comes with a Stainless Damascus Core insert. The UltraLink is a quick release belt clip for Everyday Carry (EDC). The UltraLink brings space era metallurgy to civilian hands in the form of a personal accessory that is simple and secure. It consists of two parts; the carriage, and the clip. Simply attach your keys to the clip with a split ring, insert the clip into the carriage, and attach the whole assembly to yourself or to your stuff. An integral spur on the clipped version prevents the unit from coming off unintentionally. The UltraLink was designed to appeal to fans of sci-fi inspired industrial design, but it will work for just about anyone.
