KATA3-Pack Heavy Duty Box Cutter Folding Utility Knife With Zinc Alloy Body, Quick Change Blades, Lock-Back Design, Extra 12pc Blades For Cartons, Cardboard and Boxes

Great quality! Very sharp, nice size, many blades and locks for safety.

Excellent quality, comfortable grip, lightweight, easy to unfold, easy to change blades, easy to fold after use, too. Convenient clip for secure placement in pocket.

Great work utility knife for the price getting 3 is a steal. There's not much else to say other than it gets the job done at a great price. Last knife I had of the same quality different brand cost me $12 for just one knife so getting 3 for this price is smart decision.

These are really nice knives for about a week or two of use then the screw comes loose and dumps the spring. Then you have no locking mechanism, rendering them dangerous in your pocket. This is my 3rd set and when I got them I saw nothing has changed in a couple years so not I put lock tite on the threads. Should have to.

perfect for replacing the one I broke

Not worth any money because they fail to work properly, the screws come out, and when you want to change the blade the mechanism fails. I work in a package handling facility and I am disappointed in myself for making this purchase.

All of them were sharp and ready to use. For as many boxes as I have to break down a day to recycle, they come in handy and I haven’t changed the blades in them yet.

Everything about these utility knives is great. Both have the perfect shape that feels nice to hold and is easy to use, lightweight but very sturdy, opening or extending the blade is smooth and easy, and the blade holder is such a useful feature. Comes with extra blades as well in a little holder, and they can be disassembled for deep cleaning if necessary. The price is fantastic, quality is great, will probably buy more just to have spares.
