Zero Tolerance 0350TR Tritium - Black DLC Blade - Assisted Opening

The Zero Tolerance 0350TR is an assisted-opening EDC folder with a tritium gas tube insert in the handle, a self-powered light source that glows in complete darkness without batteries, charging, or activation. If you have ever fumbled for a knife in a dark tent, truck cab, or nightstand drawer, you already understand the value. The tritium vial is set into the face-side black G-10 scale and remains visible for years.

The 3.5-inch blade is S30V stainless steel with a Tungsten DLC black coating, hardened to 57-59 HRC. S30V remains one of the most proven blade steels in the EDC market, with strong edge retention, good corrosion resistance, and easy maintenance on common sharpening systems. The DLC coating adds surface hardness and a matte, non-reflective finish.

The blade deploys via ZT's SpeedSafe assisted-opening mechanism. Push the thumb stud or pull the flipper tab, and the torsion bar drives the blade the rest of the way open. Ambidextrous operation works from either side. The handle is textured black G-10 over grey titanium liners. The quad-mount pocket clip supports four carry positions: tip-up, tip-down, left, and right. A lanyard hole is included. Closed length is 4-5/8 inches. Overall length is 7-3/4 inches at 5.9 ounces.

We have sold the 0350 platform for years, and it remains one of the most reliable assisted-opening knives in our catalog. Covered by Zero Tolerance's lifetime warranty. Free US shipping, a satisfaction guarantee, and your order normally ships the same business day from KnifeArt.com.
