Brilliant
I was skeptical about this but it really is brilliant. I use a box cutter day in and day out at work. My old 1 was getting harder to use and I wanted something that wasn’t bulky. This cutter is perfect. Cuts with ease, lightweight and easy to use. It’s sharp pointed so I wouldn’t recommend to have these on a bunch of keys unless you want a mishap.

Good but I think its over priced for what it is.
Good does what it should. But could be better.

For me, it’s okay
Seems good quality, fits well and looks good. It just didn’t really cut half of the boxes and tapes I’ve tried it on.. not bad though!

Great for opening packages
Great purchase, use it alot. Sturdy and cuts through cardboard and packing tape yet not sharp to the touch. Won't cut anything tougher than this ie cable ties. Smaller than I was expecting but just means it's less bulky on the key chain

Still going strong
Purchased this year's ago working taking in delivery and stocking a store where they don't trust is to have anything sharp. It now looks like somebody chewed on it but still works great even when used for way beyond its intention

Huge Disappointment, Do Not Buy!
Straight to the point, this is trash! I'm not one for putting bad reviews at all but unfortunately this is one of those that needs it. It is advertised as a "box cutter" it can cut tape of parcels, open envelopes but the main point of my star rating is that on the first box I opened, cutting the tape.. it's made a dent in the tool already. Not strong and certainly not worth £10. A piece of plastic equally does the job. I'm sure few more uses this will be straight in the bin. Really disappointed, may aswell just burnt the £10 note instead.

Mine came damaged
Overall these seems like a decent product, would've like some sort of harder more sturdy material for the product but the material they've used seems to be decent, and adds no weight to your keys at all - however if it arrived damaged from the packaging or transport or something, how well is it gonna do long term on a keyring? The damage (as you can see on the photos) doesn't seem too bad at first but when attempting to cut some tape on another Amazon package that came, it proved fairly unusable as the little dent on the blade itself makes it very hard to cut things. I'm going to return this one - I'll think about getting a replacement but I'm not sure right now.

Works well
Bit short so hard to hold but fits the smark key ring fine

Okay
It’s good for what I paid and what’s it made for but the blade got a little big jagged after just a few boxes but after that no other “damage” on it.

¡Plástico!
La misma descripción del producto lo dice: es plástico. Pero no está demás recordarte que es de plástico, y que por lo tanto sufrirá desgaste el producto después de haber usado varías veces para abrir cajas. Si puedes, te recomiendo que busques otra opción en metal.

Worth it
Don't know what all the negative review is for it a safety knife it cuts what it intended for it not made to cut skin. People thought this cuts skin? 🤨WTF it even says it not a box cutter or a razer 🤨. It to cut envelope and cut open taped box it not like it cut metal 🤔 that like taking a pool noodle and trying to open a car door.
