Meet the Three Rivers Manufacturing Pit Bull OTS Auto, a compact American-made automatic knife that brings serious cutting performance and plenty of snap to your everyday carry. As TRM Knives’ first automatic offering, the Pit Bull fires open with a simple push of the button and locks into action with an authoritative thwack that’s sure to put a grin on your face. It’s a fast, capable folder built for users who appreciate precision engineering, premium materials, and a little extra excitement in their EDC.
The Pit Bull’s profile may remind you of the popular Neutron 2, but its slightly thicker and more robust construction gives it a substantial feel without adding unnecessary bulk. Measuring 7-3/16 inches open and just 4-1/4 inches closed, it slips easily into your pocket while still filling your hand comfortably when it’s time to work. The handle combines intricately milled, 3D-contoured aerospace aluminum with a contrasting blue denim Micarta inlay, creating a distinctive look and a secure, comfortable grip. At only 2.95 ounces, it delivers an impressive balance of strength, usability, and carry-friendly weight.
At the heart of the Pit Bull is a 3-inch blade crafted from CPM MagnaCut, a premium powdered stainless steel known for its excellent combination of edge retention, toughness, and corrosion resistance. The .110-inch blade stock strikes a smart balance between the ultralight Neutron 2 and the more substantial Bulldog. Its tall, full-flat grind creates an efficient cutting geometry that makes short work of everyday slicing tasks, while the deburring and two-stage ceramic tumble and polish finish gives the blade a clean, refined appearance.
Deployment is quick and intuitive, making the Pit Bull an excellent choice when one-handed access matters. A deep-carry 6AL-4V titanium pocket clip keeps the knife riding securely and discreetly in your pocket, while the compact 4-1/4-inch closed length makes it easy to carry throughout the day.
Proudly made in the USA, the Three Rivers Manufacturing Pit Bull OTS Auto combines premium MagnaCut steel, aerospace aluminum, blue denim Micarta, and precision American craftsmanship into one exceptionally capable automatic folder. It’s compact enough for everyday carry, robust enough for serious cutting, and distinctive enough to stand out from the crowd.
