Tape King Utility Knife Box Cutter Razor Set (12-Pack, 9mm Blade Cutters) - Retractable, Lightweight, Compact, Extended Use for Office, Home, Arts, Crafts, Hobby for Cutting Boxes, Cartons, Cardboard

Cheaply made. Some didn't even work. The blade would not come out.*Update: seller generously sent me a new set of larger blades and they work great. They think I was sent a bad batch of the smaller ones, as I stated previously, some of them would not work. All of the larger ones work and I am happy with the outcome. Good company that helps when you have issues.

Man these things are cheap. The lock doesn't actually lock the blade. They barely can handle cutting packing tape. They're sharp but waaaay to flimsy. That almost makes them dangerous to use. I would not cut a box with these - they're not up to the task.Edit: 1-23-18.After posting this review the seller contacted me and issued a refund. They also sent me a larger model at no cast that is functional. So although this particular smaller box cutter model is still a 1 star product in my mind - the service is 5 stars. Just buy the size up from this model and you'll be good. The quality is much improved.

I started using these about a week ago, they are great for their price. They were a little smaller than I expected, but it was me who didn't read the description clearly but they do the job nonetheless. I've been using these to cut eva foam, cardboard, and poster boards and they do their job well. I don't expect to use these for something heavy duty like in construction, but anyone can tell from reading the description as these are lightweight compact 9mm blades.

They don't win prizes for high quality or heavy duty but hey, there are 12 of them and they do work for small cutting jobs. Now you can put one in every room, garage, car, shed, office, boat, other house, other car, purse, European carry-all, briefcase, airplane...it's hard to have too many utility knives.

Product review - one starNot only flimsy, it can be dangerous if you keep it in your pocket because the blade can come out to hurt you. I ordered it only because of its small size. I thought it would be small enough to keep it in the pocket but it's not safe at all.Seller review - five starsAfter I posted product review above, Tape King offered me a complimentary knife set, which come with bigger standard size utility knives. They look a little rough but work as expected, not bad for the price. I give five stars to the seller for their effort to satisfy customers.

Blade does an ok job and the locking feature does not lock. I use these for weeding vinyl and it makes the process quite difficult when I need to apply decent pressure and the blade pulls out or pushes back in. I’ve tried a few from the box and so far all have had the same issue. The blade is sharp but not as sharp or smooth to use as other I have used. Sometimes I have to make 2-3 passes for it to cut through vinyl. Will not buy again.

These are flimsy. There is no pocket clip. The lock comes apart easily. I wish I had bought stanly brand.

I was looking for the classic orange ones but couldnt find them so i got these. These are awful. I dont write reviews generally but felt compelled. First one i used the manual lock feature broke off. 2nd one i tried the knife wouldnt even expand, it was stuck, 3rd one had the bottom black piece fall off.4th one i didnt even try, just chucked the whole box. Go to home depot or lowes and just get yourself a metal stanley for 2.95. This was an egregiously awful product.
