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.

Definitely beats sleeping on the floor!
Color: Grey, Size: Twin
I was sleeping on the floor with my dog after she had emergency surgery and this helped me get through those tough couple of weeks. Comfortable and not too heavy. Comes with a bag to store it in and helps make it easier to move around.

More Comfortable than an Airbed
Color: light gray, Size: cot
I purchased this 4-inch foam floor mattress for when grandchildren stay over. This is my 2nd one, since zi have 2 grandchildren. I don't have room for beds or bunk beds, but I have a space where I can store these. I slept on it myself several nights in a row when I had company and I found it to be much better than sleeping on an air bed. I purchased mattress covers and fitted sheets that fit the exact dimensions of the mattress and I am happy to be able to provide a perfect sleeping setup for my 2 grandchildren! If you have a place to store the mattress when it's folded (25 inches high, 31 inches wide, 12 inches deep) I recommend a 4-inch thick foam floor mattress over an air bed. In my home it is the perfect solution! Follow all the directions for allowing the mattress to reach its full thickness. It is vacuum packed and needs several hours (almost 2 days) to expand.
