10PCS Box Carton Cutter Utility Knives Retractable Snap-Off Knife Razor Blades

Poor snap. I like the blades (and the price!) but once you've dulled the tip, the cutter is pretty much done. Other brands have scoring on the blades so that one can snap off the tip to get a new sharp edge. These cutters are very lightly scored and impossible to snap in the desired place. It really lessens the cutter's life.

So many things you can use these knifes for. I have them all over my house for whenever I need them.

Not quite the same quality as those that I've gotten at hardware stores -- the plastic is softer, the black thumb-push part has sharp edges. The blades seem to be good quality, but I find them (all of them) difficult push/pull in an easy motion with the thumb, which makes them close to worthless. I'll probably take the blades out and use them to replace the used blades the ones I already have. As for color variety? -- I got 5 dark blue and 5 black... I was hoping for a little more variety. Only $10, but I wouldn't buy again.

Good deal, use these alot.

We have to cut open several boxes a day for deliveries. I had more expensive box cutters that would constantly break and would not feed the metal. This is our second order of these, and the reason for replacing was not for breakage. They tend to get lost because they are small. But it's not a huge loss when they do as these are super affordable.

Very cheap. They don't retract smoothly. I would spend more for a better product.

does not hold the lock, and few are hard to push up

Great product. I was having so much stuff shipped to my home and I cutting cardboard for months. It was great to have multiples. I one ov those people that can lose things without moving. I just go to my toolbox and get another to use until I complete my tasks. I'll find the missing one later it's usually buried under cut up cardboard.
