Slice 10585 Manual Carton Cutter, Ideal for Boxboard & Thin Corrugated Cardboard, Lightweight & Portable, Finger-Friendly Ceramic Blade, Ambidextrous Design, Lasts 11X Longer Than Steel

This here is perfect for factory job roles and so forth. The knife is sharp, and stays sharp. The knife is reversible, so if you feel the job isn’t going as smooth with it getting blunt, just flip the knife blade over. This glides through thick cardboard all day long, makes easy work of it infact. I haven’t had one issue with this, and I use it all day long. The other reviews concerning people complaining have picked the wrong knife for the wrong trade. 100% recommend!

Just what i needed. Great durability, function, design and easy to use. Perfect size and safety. Highly recommend.

These are amazing... They cut cardboard and tape with absolute ease, however they do struggle with plastic straps, I had to use an alternative for the straps, but to be expected, if you're just cutting boxes and tapes use these, forget stanley knives, you can rub this (you probably shouldn't though) over your hand and unless you're applying A LOT of pressure it won't cut you. Overall 10/10 highly recommended.

Blade is great for cutting,but I have ordered pointed blades,it’s a shame the cutter does not lock in out position,and did not retract so easily

It does what you need it to do and will likely last a long time if looked after. I will say that the inner section can fully slide out, which is an unusual choice and means this Carton Cutter doesn't get as much use as it might have.

Love it. Makes opening boxes so much easier. Simple tool.

Very happy with this, as a box ripper it works very well, no fear of cutting my hands or the contents inside the box. received in good time and packaged well.

Very happy with the cutter. Does the job really well
