This Tanto-style military folding knife from ZT features SpeedSafe manual assisted opening for one-handed blade deployment. Just push on the ambidextrous thumb stud or pull back on the blade protrusion. The modified Tanto blade in S30V stainless steel provides extreme strength and is coated with Tungsten DLC (Diamond Like Carbon) for a non-reflective matte-black finish. The 0400 is one of the thinner folding knives in the ZT line, which makes it excellent for compact carry. While the front scale features friction-tape inserts for a secure grip, the back scale does not have the tape, enabling an easier draw and storage in the pocket. A 5/16-inch pivot shaft adjustment enables tighter or looser blade deployment. Includes a dual mounting system for tip-up or tip-down, right-handed clip carry.
