Zero Tolerance 0203 DuraLock Knife

The Zero Tolerance 0203 is a purpose-built EDC and tactical folding knife designed for serious work and uncompromising reliability. This full-size knife is made in the USA and blends rugged function with high-end build quality. Whether you're on the job, in the field, or just need a dependable everyday tool, the ZT 0203 stands ready. It’s a manual folder that opens with authority and locks up solid, all wrapped in a clean, mission-ready package.

At the core of the 0203 is a 4-inch drop point blade made from high-performance CPM M4 steel, known for its outstanding edge retention and toughness. With a Rockwell hardness rating of 60–62 HRC and a black PVD-coated finish, the blade is built to resist wear and extreme toughness under hard use. The plain edge and balanced profile make it ideal for both precision cutting and heavier-duty tasks. Thumb stud deployment on smooth washers ensures reliable, controlled opening.

Built with olive G10 handle scales, the ZT 0203 offers a solid, comfortable grip that’s ready for work in wet or dry conditions. The ambidextrous DuraLock crossbar mechanism keeps the blade securely open during use, while the reversible deep-carry pocket clip (tip-up, left or right) ensures discreet and adaptable carry. The blade runs on solid-state phosphor bronze washers for outstanding smoothness. Black-oxide hardware and a black Cerakote clip add to the knife’s low-profile, tactical appeal. At 6.6 oz., this knife strikes the right balance between size, strength, and carry comfort.

Every 0203 is backed by Zero Tolerance’s lifetime warranty and a reputation for overbuilt quality you can trust. When you buy from KnifeArt.com, you get more than just a great knife—you get expert customer service, fast same-day shipping, and peace of mind knowing you're dealing with professionals.
