Before Pro-Tech was Pro-Tech, Dave Wattenberg was hand-assembling the original Runt at his kitchen table. The Pro-Tech Runt 5 is the fifth generation of that founding design, and it has grown into the company's best-selling automatic: a 1.96 inch blade that delivers the full signature Pro-Tech snap in a package built for the strictest blade-length rules in the country.
The sub-2 inch blade is CPM MagnaCut, the modern benchmark for edge retention and corrosion resistance in one steel, broken down in our knife steel guide, offered in your choice of Wharncliffe or Reverse Tanto profiles. The fifth generation redesigned the 6061-T6 aluminum handle with a squared profile and integrated jimping that makes the 3.25 inch frame feel far more substantial than its 2.08 ounces suggest, and the button lock plus tip-up deep carry clip complete a knife that vanishes into any pocket at 5.13 inches overall. Pop the button and the coil spring fires with a level of torque that surprises everyone the first time; the action is pure Pro-Tech, just concentrated.
California caps legal automatic knives at blades under two inches, and the Runt 5's 1.96 inch blade is engineered precisely for that line, which is why it has become the go-to auto for Californians and for anyone else facing similar blade-length limits. As always, know your own local laws before you carry. Beyond the legal angle it handles real everyday work, packages, cordage, food prep on the tailgate, and configurations run from hard-anodized black and OD green workhorses to limited runs with hand-ground Mike Irie mirror blades and abalone button inlays that sell out on release. Runt drops disappear quickly, so if the version you want shows out of stock, sign up for restock alerts and catch the next batch the moment it lands.
