Premium Steel, Compact Auto, Big Performance

The Pro-Tech Runt 5 takes one of the company’s most popular small automatics and gives it a serious upgrade. With a premium MagnaCut Wharncliffe blade (unless otherwise stated) and precision-machined aluminum handles, the Runt 5 combines cutting-edge materials with Pro-Tech’s legendary automatic action.

At just 3.25 inches closed, it practically disappears in the pocket, yet the 2-inch blade deploys with authority using Pro-Tech’s push-button mechanism. Compact, legal in most regions, and perfectly tuned, the Runt 5 is an ideal choice for everyday carry.

Note from Lone Star Knife & Supply

I’ve always loved this model for what it represents: pure precision in a small form. The MagnaCut Wharncliffe blade is built for real use, from packages to precise cutting tasks. Whether you go with the bright Blue or the classic Black, the Runt 5 delivers everything that makes Pro-Tech great, just in a smaller, faster package.
