Customers say

Customers find the box cutter cuts great, particularly through cardboard boxes, and works as well as standard box cutters. They appreciate its ergonomic design that's easy to hold and handle, and consider it safer to use than traditional ones, especially around children. The durability and sharpness receive mixed reviews - while some find it sturdily made and the blade stays sharp for months, others report it breaks easily and isn't very sharp.

Makes quick work of opening boxes, safe to use. Not the best for cutting into cardboard
5 out of 5 stars
Makes quick work of opening boxes, safe to use. Not the best for cutting into cardboard
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.

    I bought this box cutter because it was advertised as safer than your regular box cutter. Historically, I have often cut myself with standard box cutters. I have found this one very easy to use and I have not cut myself once. It even has a great design, which is much more usable than your standard one. I think I recall that when I bought it, the detailed description said that the blade (ceramic?) lasts much longer than the usual metal blades. I have actually purchased 2 of these because I keep them in different places in the apartment, and neither of the blades has gotten dull. Great product!

    Reviewed in the United States on May 15, 2025
    Size: 10400Color: Locking BladeVerified Purchase
    This box cutter really stands out for how safe and comfortable it is to use. The ceramic blade is sharp enough to slice through cardboard and packing tape easily, but not so sharp that you’re constantly worried about cutting yourself. It’s a great option if you open a lot of boxes at home or at work and want something a little safer than the usual utility knife.
    The handle has a unique shape that feels ergonomic and solid in the hand—it doesn’t slip or strain your wrist. I also appreciate the three-position manual slider, which makes it easy to control how much of the blade is exposed.
    That said, it’s not the best tool for super tough materials like thick plastic strapping, and the handle might feel a bit bulky if you have smaller hands.

    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.

    I purchased this to break down cardboard boxes for recycling. However, while comfortable to hold; the blade is so small that it doesn't cut through cardboard. I have to go over the cut several times until it goes all the way through so I have to be careful how I use it.
