RBAYSALE Utility Knife Folding Heavy Duty Carpet Cutter with 5 SK5 Blades 420 Stainless Steel Retractable Box Cutter with Safety-Lock Design Craft Tradesman Knife 180g

I use box cutters in work for doing just that - cutting cardboard boxes and plastic strapping. I have used many knives (Stanley FatMax, Rolson, etc) they have performed ok until they somehow get broken, but this knife has beaten then all. It is such a sturdy knife. It fits the hand just right and the blades fit well without movement (just make sure you get the right size, not all blades will fit resulting in blades being loose or falling out).There is a black button on the side that you push up to open the knife and to change the blades.TO CLOSE THE KNIFE: You need to push the NOTCHED BAR to the side whilst closing the knife (see my photos) It is then safe to store.All in all, a very good utility knife and I recommend it without hesitation.

Used to cut flooring, easy to use, change and very sharp,

I've had this know for 3 years it's still as good as new, i believe that's because it is very well made, fits in the hand nicely, like all these knives the blades are very sharp, i would recommend this knife as well as the seller. the 3 pictures are after 3 years and i do use this knife quite often.

Nice and sharp utility knife foldingI got it to fix my carpet, and the blade that goes through it is pretty sharp.Easy to fold and compact sizeOverall, I am delighted!

This knife is of the finest quality, at this price it’s not worth buying anything else.

Good price and good Quality

Was very surprised at how easy and effective it was cutting through the carpeted mat I bought.
