The new, all-black ZT 0300 and ZT 0300st join ZT's mission-ready line of made-in-the-U.S. knives. The aggressive combat knives feature ZT's quad mounting system and SpeedSafe manually assisted opening. With SpeedSafe, the blade can be deployed one-handed with an ambidextrous thumb stud or index finger protrusion. The quad mounting system lets the user mount the clip tip-up, tip-down, on the left side or the right. Both ZT 0300 and 0300st feature S30V stainless-steel blades with matte-black Tungsten DLC coating. The S30V provides durability as well as wear and corrosion resistance. The non-reflective DLC (diamond-like carbon) coating enhances hardness and reduces friction drag. For extreme mechanical strength and a secure grip, the blade is paired with 3D machined scales of super-strong, black G-10 and titanium. A titanium frame lock keeps the blade secure. Field adjustments can be made quickly and easily using the hex head pivot shaft nut. The blade is made of S30V stainless steel, Tungsten DLC coating, 3.75 inches long, .156 inches thick and the knife weighs 8 ounces.
