Slice Auto-Retractable Box Cutter, Heavy Duty Utility Knife, Safe Ceramic Blade Lasting 11x Longer than Metal, 1 Pack

This box cutter works great and feels safe to use with the ceramic blade. Easy to hold and cuts through boxes without much effort.

This is simply the best box cutter I've ever used.It's easy to hold, cuts accurately, evenly and smoothly, and best yet, doesn't cut you if you touch the blade. The lock mechanism is secure and easy to engage/disengage, and the blade stores firmly within the cutter. This is an innovative and functional box cutter with a unique design. The only drawback is that you have to use proprietary blades, one is included preloaded in the cutter, but given the benefits this is a fair tradeoff.Highly recommended.

This is a good safe knife to use when you are trying to cup open boxes. I normally need one that can be used to cut boxes to make them easier to throw away. It makes quick work of cutting the packaging tape but it is safe enough to not cut you which is good. Regardless it safety retracts and stores the plastic blade. You have to actually press and hold the button down to extend and retract the blade. This makes it so the knife cannot close by itself by accident when you are cutting. You can flip the blade around but the material has yet to go blunt. The blade itself can also be easily replaced all you need to do is press and unlock the cover to expose the blade. You then can replace it with a new blade. You need to replace it with a slice blade. What is nice about this blade is that only half it is actually out so when the one side gets dull you just need to turn it around and presto you have another blade to use. Again the blade has yet to have issues. The grip is pretty secure and there is a belt hook so you can put it on your belt without worrying about it falling off. You have to find some kind of ring or hook to attach to it though. It is not included. This can cut most small boxes as well as tape which is great for me because I always have a ton of boxes and mailers I need to open. The orange color is not bad but it see darker near the tip piece. Because it has no real metal, it is not prone to rusting. This means it can get wet and you can easily clean/dry it out without fear of damaging it. Overall I think this device is pretty nice. It is definitely a good utility knife to have around as it is safe, sturdy, and cuts through packaging tape without worrying about cutting yourself.

The blade on this is the pretty standard Slice ceramic blade. A little more expensive than steel razor or carpet cutter blades, but they're pretty durable if you don't twist them. They say this device has a 3-position blade, and I'm assuming that's fully open, half open, and closed. The half open (blade halfway out of the shaft) is probably useful for letter opening or maybe for cutting tape on delicate postal packages. I never use it. I always have it either closed or fully open.The device cuts as well as the blade does. The blade that came with it works fine for opening the boxes we get on containers from China, and for cutting open shrink wrap on pallets. The only reason why I didn't give this thing a fully 5-star rating is because it's kind of big. That hook on the butt of it serves a purpose, and you can definitely just push the thing down against a pallet or a box and be able to cut the tape or wrap from it, but it's pretty big in your pocket, and you really have to hold it just the right way to get it to cut well. When you have to cut a pallet wrap that is not directly against the side of a box, it takes several more swipes to get done than with a normal box knife.Maybe if the blade extended a little further, this wouldn't be an issue, but on the model that I have, I mostly just use it as a box opener, not for cutting open pallets, and having to use two tools doesn't help my productivity all that much.Good design and idea, maybe needs a little more finessing.

Excellent choice for my job. The blade lasts a while but you do need to purchase the replacement blades. The grip is good.

Look, is this AS sharp and AS good as a cutter with a traditional blade? No. However, if you really are just using it to open boxes mostly, you don’t need something insanely sharp. And if you have kids around, it can make you anxious about the idea of them finding where you keep the box cutter.I was hopeful that this would be good, while trying to keep my expectations low, since it didn’t have a sharp blade. However, to my surprise, it not only cuts just as effectively, but also with almost no extra effort than a traditional box cutter. Any time I have needed to use this, it worked exactly how I needed it to. Furthermore, the ergonomic design actually does make it easier on the hand to cut when you have to break down a ton of boxes. And you really do need to apply a good amount of pressure to break skin with this blade. I recommend this over any alternative by far.

My job requires opening shipment boxes regularly. After cutting my thumb in the same spot with a dull blade numerous times over the years, I decided to “invest” in a better box cutter. After using for a few months I highly recommend this box cutter. The quality is great and the ergonomic design makes it easy to use. The blade has remained sharp (estimating 200 +/- boxes opened thus far). Most importantly, it met my one requirement — the curved handle prevents me from cutting my thumb on the opposite hand.

Have to push it out and cut- good safety feature but harder to use. You have to push and cut at the same time, otherwise blade will retract.Wish it’s a bit sharper.
