Corrugated Cardboard Cutter Handsaw with Cover [Dan Chan], Safety Box Cutter Package Opener Tool, Made in Japan, Orange

This is a surprisingly handy tool. It cuts through cardboard ok, but I usually use it to cut the tape which it does really easily, and the rounded end means I'm not likely to damage the contents. Much safer than a pair of scissors.

Very handy item. I've used it as a letter opener. Cardboard cutter as it's intended and even on celotex insulation. This is a quality product in my personal opinion and would recommend it to anyone.

I LOVE tools and for the price this is a gem. The only reason I didn’t give it a 5* is because the noise (sensation) of cutting cardboard with this implement goes through me, similar to hearing a blackboard being scraped. I wouldn’t say it cuts through cardboard like butter, but you don’t get the same fatigue when dissecting large amounts when your utility knife goes blunt.

Great tool for cutting up cardboard whether it’s for crafting or just making bits of box smaller for the bin. Acts more like a saw than a box cutter but watch your fingers nonetheless.

I love this! Previously used either a pen knife or Stanley knife for opening packages. But with toddlers, didnt quite feel safe. This is more like a file. Or a dual sided butter knife. There is a trick to slicing cardboard. Let the knife do the work, let the serrations do their work. When you get it, goes through like butter.

My initial impression of the knife was does this thing honestly work? It is so much better than a box cutter at cutting cardboard and makes much lighter work of it.
