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.

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!

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

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

Don't be quick to buy
Flimsy, bends, came with same chips as other review say, only use if the corner with doesn't always work the best or you press really hard, good size though, not much ease of opening, functions mid, not the sharpest either but dull enough to stay safe. I only got as can't find alternatives online.

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.

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.
