Designed from parameters given by former elite special forces members, the TX399 Knife is one of the founding members of our tactical collection. Utilizing our Double Lock technology, any operator can work with confidence knowing that the added safety prevents the knife from accidentally closing. It easily opens with one hand using a reversible thumb stud, and you can adjust the two position pocket clip to adapt to your carrying style.

With Coast’s commitment to quality, the TX399 Knife is backed by Coast’s lifetime warranty against defects in materials and workmanship.
