Back Folding Box Cutter
Drill Doctor 750X Stanley knives (box cutters) are always handy to have around. I've used them for the last 50 years and would never be without one. The blades are replaceable and cheap so you are not worried about damaging them with an overly ambitious cut.

Speaking of replaceable blades, I have always thought that was also the Achilles Heel of the Stanley knife. The concept of a replaceable blade is great but having to go get a screw driver and open the knife up to replace it is pretty ordinary. Not to mention trying to keep an overload of spare blades inside it while you do it back up.

Enter the folding box cutter with its quick change blades. When I saw this I thought it has to be worth a try so have a look at the video and see what I thought about it.
