Zero Tolerance—Tough Materials, Tough Tech

Designed and manufactured to stand up to heavy-duty use, Zero Tolerance Knives are built of premium materials such as S35VN or 154CM blade steel and 3-D machined G-10 and titanium handles. All ZT knives, whether folder or fixed blade, are made to provide the user with maximum strength and versatility. The knives have earned a reputation among their devoted fans for being “a real beast” or eve—proudly—“overbuilt.” All Zero Tolerance knives are made in the United States of America and are built to conquer just about anything.
