The Zero Tolerance 0300 Black Assisted Folder is one of the most iconic hard-use knives ever produced by Zero Tolerance, built for extreme durability and tactical performance. Co-designed by renowned makers Ken Onion and Mick Strider, the ZT0300 set the benchmark for overbuilt folding knives and remains a favorite among collectors and serious users.
Featuring a robust 3.75-inch CPM-S30V stainless steel blade, this knife delivers exceptional edge retention, corrosion resistance, and toughness. The black-coated blade provides a low-profile, non-reflective finish ideal for tactical and outdoor environments. With its SpeedSafe assisted opening, deployment is fast, smooth, and reliable—ready when you need it most.
The handle combines textured G-10 on the front with a titanium frame lock on the back, ensuring a rock-solid grip and secure lockup even under heavy use. Designed for versatility, the quad-mount pocket clip allows multiple carry positions to suit your preference. Built like a tank, the ZT0300 is a true workhorse knife—now discontinued and highly sought after by enthusiasts.
