  • Stonewashed reverse tanto blade made from CPM-20CV steel.

The Runt 5 automatic knife is Pro-Tech’s newest take on their classic Runt model, and boy does it look good! It features the superb opening action that Pro-Tech is known for, and a sub-two-inch blade, making it legal in California. The handle is small, but well shaped to fit the human hand, making it comfortable to hold; texturing on the back of the handle at the base of the blade makes it easy to maneuver the blade for precise cuts. This pocket-friendly auto comes with a secure pocket clip and lanyard hole, and is sure to put a smile on your face each time you reach for it.

This is a sharp-looking knife. It has some weight to it for its size. The blue is striking - an ‘upscale’ friendly-looking knife - until you press the button. No wrist snap, thumb flick, finger roll - this just opens with ‘a vengeance’ and the thick blade looks like it will take some abuse. I’ve learned to open it ‘slowly’ with my fingers slowing it down. Small blade substantial tool. With a little practice, it closes easily with one hand. Highly recommend a nice companion to my Spyderco and Benchmade knives.

Love Pro Tech

Yes it's small, yet does not feel like it in hand. Wicked sharp right out of the box, pops open incredibly fast

Just received this blue Runt 5 today and although it is my first Pro-tech, I had high expectations due to their reputation. I am not disappointed! I was on the fence about dropping so much $$ on such a small knife, but wanted to try Pro-tech and add a small auto to the collection. It feels like perfection and the fit and finish is absolutely flawless. Great little auto for everyday tasks, and shouldn’t scare people like a large one will.
