Fantastic.
I bought this for boxes at work and I'd be lost without it. I've not struggled opening anything and it stays sharp. It does not cut you or any countertop. I must get another for at home as I'm truly impressed by this pen type opener.

Brilliant box cutter. Super Safe.
These range of Slice safety cutters are excellent. They have the ability to chop though paper, cardboard and plastic packaging with ease but it is almost impossible to cut yourself. The ceramic blade make this wonder of physics possibly and stay sharp ages. Only negative is the price but excellent for elderly people or children as super safe.

Amazing for cutting through tape
The quality of the knife is amazing. The blade is just sharp enough to cut through tape but not enough to were you can seriously harm yourself. Only issue with this product is the ease of use with it being slightly awkward to get the blade from it's hidden state to its open state.

Opening boxes is like putting a hot knife through butter!
These are brilliant. A work colleague lent me hers at work as I had taken in a large delivery and it saved me so much time. I actually bought 3 they are that good - for me, my husband and my daughter-in-law

Good blade, auto-retract mechanism makes it useless for crafts
I wanted a craft knife but this is more of a box cutter. The blade retracts automatically when you let pressure off of your thumb. So I can’t use it for fine work. I didn’t realise when I read on the product listing, that the blade retracts automatically, that there would be no way to prevent it from retracting. I checked on Google, YouTube etc and it seems to be so. I’m keeping the knife as a safer way of opening all those Amazon boxes. But it’s no use for crafts.

Very handy
I originally got this ceramic knife as a scraper when using coloured pencils, but it's also not bad at cutting too and very safe to use. I'll mainly use it for scraping off colour pigment off of paper though which it's quite good at.

Good but extremely expensive
It was about £15 when I first buy it, don’t know why it raised up to more than £30 now when I try to get a second one.

Small and slender
Have to use these type of knives for work, as blades are not allowed. Quite small blade, but does the job.

Safest option for a cutter
Safe and rugged. Will last forever as it won’t rust like other cutters.

Ideal para abrir empaques de envíos
No se le pega el pegamento de las cintas q corta cuando abro empaques!. No tiene el gran filo, pero es perfecto para las cajas q recibo de Amazon, así no maltrato mi navaja Suiza con el pegamento de los empaques q siempre deja residuos.

Great tool
Great tool! I use to apply the subtraction technique on my colored pencil work on duralar. It has a rounded /not pointy edge and works very well!

Ottimo
Utensile essenziale se come me siete soliti ricevere molti pacchi e non volete qualcosa di troppo ingombrante e soprattutto riduce il rischio di tagliarsi. Super consigliato

An average buy
It's not exceptional.The grip isn't very good as it's a bit bulky and the area of work gets hidden beneath the unbuildy body.
