This is a perfect cutter!

I was tired of looking for my siccors to open packages from the mail.

I has a magnet on the back so you can stick on the fridge and never lose it.

It isn't super sharp so you can't really hurt yourself by accident but razor sharp enough to help you cut and open packages etc.

The only thing I wish it came with was another replacement blade in case the one it comes with gets dull or breaks. I highly recommend this item since I use it all the time :)

Easily Opens Taped Boxed and Packages

Reviewed in the United States on July 13, 2024

This cutter is great at opening tapped boxes and packages received in the mail along with other packages of food items. I've purchased a couple and one is on our fridge in the kitchen using the built-in magnet. It is so easy to use and safe with the slide to make the blade invisible along with the ability to lock so it can't accidentally be opened. Very useful tool.

Pocket Sized & Durable

I bought this because I noticed the patent on the blades compared to other ceramic box cutters. I figured they might have a specific manufacturing process that makes them less likely to cut you? Idk just my assumptions but I can assure you the blade is safe to touch. I'm sure if you wanted to hurt yourself or someone else the tip/corner could certainly hurt but you would have to try. And an accidental cut with one of these just isn't going to do the same damage as a traditional metal blade.

Having gotten stitches from knives, I can say confidently, this blade does NOT feel capable of doing the same damage. It will not go thru skin like butter, it would be more like a rip or gouge on a sharp corner.

That said I'd still suggest supervision if kids are using it. Personally, I work around kids and if I dropped it by accident and one of the little ones found it, I wanted peace of mind knowing they were a LOT LESS likely to hurt themselves or others before I got it back.

The blade outlasts the housing.

I love this little box cutter. I have cut the tops off of sooooo many boxes, hundreds a day sometimes and we'll this thing absolutely performs. I cut boxes faster than any other person around who has those lame penguin cutters. This always cuts smooth, fast, and super easy. I LOVE IT.

With that said, this is my second one, and I cut hundreds of boxes a day sometimes, and as you can see the wear on the blade housing is giving way to the point I always have my blade "open". Its not as safe but I cannot give up this beloved box cutter.

I am going to buy a new one, the green one that retracts so I'm compliant at work and I will continue to do so with the hopes that one day, they or someone else makes a blade of similar quality in a better housing that is as convenient to carry as this one.

If you want a box cutter for your house and see yourself cutting a much smaller amount of boxes than I do at work, let me tell you this is the one you want. If at work you can get away with less safe box cutters, they're probably a better option as this housing degrades so quickly. I will suffer with the best I have to work with, because with cutting as many boxes as I do, I always want them to perform as well as this one does every single time.

Please slice, make a more durable housing for this model ????????

Better than I thought it would be

Reviewed in the United States on April 10, 2024

honestly, this product works great. i was skeptical about how it was going to cut because the blade is not sharp at all but it actually works better than a sharp blade. my only issue with it is that it is not ambidextrous where the slide button is only on one side.

i read the reviews before i bought it and a lot of people were complaining that the blade wouldn't lock with the lock switch, but i don't think they realized they bought the self retracting model and the lock on the bottom isn't to lock the blade in place, it's to lock the blade housing so the whole thing doesn't just fall apart randomly or when it gets dropped

Don't come to a utility knife fight carrying a Slice

Reviewed in the United States on September 23, 2017

I've seen ceramic cutters but never used one. I have ceramic knives and veggie cutters that cut very well. I carry a Bessey in my pocket but it is quite heavy so I wanted to see if I could lighten my daily pocket load by switching to a Slice.

The Slice size and weight are very nice. It weighs almost nothing and it fits easily in my pocket. It's about the size of a box of square Tic Tacs.

::::The lanyard hole::: It is meant for a lanyard and not a keyring. Lanyard threads will fit but most split keyring holders will not fit. It is tiny and I had to use a single wire ring, with a wire diameter less than 1mm (probably about 0.5mm).

::::How does it cut?:::: It's ok but it's no match for my Bessey. I've been carrying both the Slice and the Bessey for three days and attempted to use the Slice as much as possible. I wanted to see if the very lightweight Slice could replace my much heavier Bessey (7 ounces) for most of my general cutting/opening needs. Unfortunately, the Slice just doesn't have the cutting power nor depth of a heavyweight utility knife. In many cases, the Slice wouldn't cut through thin plastic -- it would only score it (like clamshell packaging). Even with a week-old blade in my Bessey, its metal cutting blade is much sharper and much more effective. For far too many applications, I found the Slice to be frustratingly less effective than a metal cutting blade. I had to forego the Slice for the Bessey most of the time.

::::Sticky packaging tape:::: Certain packaging tape gets tacky in elevated temps and it will stick to a blade. This means you must disassemble the Slice and clean the interior housing and blade. With a utility knife, you just snap the end of the blade. If the Slice is used to cut through lots of tacky tape, it will render it almost useless. When that tacky goo hardens, it's even worse.

::::Bubble envelopes:::: I used the Slice to open a bubble envelope.Not using a flat surface and cutting above the bubbles, it was very difficult to open the package. The small blade kept pushing the mailer away. Using a flat wooden surface and cutting the other end (below the bubbles), the Slice worked much better but only partially opened the mailer. However, it scored the remainder well enough that I was able to pull it open by hand.

:::: Regular packaging tape (like Amazon uses):::: As long as the tape is applied to a perfectly shaped and perfectly closed box, it works fine. Along the top, it cuts well. On the sides, if there any irregularities (top is askew, box is dented, etc. ) and this makes the depth required to cut the tape greater than 1/4 inch, then it cannot reach the tape. I used the Slice to open over a dozen boxes and with almost every boc, it left some portions uncut. However, it took minimal time and effort to rip the remainder open.

:::: Corrugated boxes:::: Cutting a box into pieces along the fold lines works decent but takes multiple tries. Cutting through the actual corrugated sections is much more difficult. If you downsize (cut) the boxes for recycling, the Slice will do it but it takes a lot more time and effort than a regular box cutter.

Don't get me wrong. The Slice is a nice tool for certain applications. It is lightweight and easy to carry. It doesn't have a fixed blade but the retractable blade shouldn't be a big issue unless you must use a blade all day, every day, in your work/hobby.

If you don't need a serious cutting tool, get a Slice.
