Staples Retractable Knife
on April 23, 2026
Posted by: Cindy Myers
I am extremely disappointed. I purchased several of these a few years ago and they worked beautifully. I just bought 3 more and while they work fine, all 3 were sealed 8n new packaging but all 3 for extremely scratched on the side. At first I thought it was just packaging that got stuck to glue from the packaging but they are scratched up like they were damaged and just repackaged as new.

For use at home for opening boxes. Works better than scissors. Don't know how long will hold up but for light use is good.

I had a utility knife that looked like this one but the blade was dull and the outside was rather beat up after a decade or more of frequent use. This one is so strong and sharp that I able to cut a cardboard box with it. Not just the packing tape but the actual box itself. I have to be careful that I don't cut the contents inside!! We used to call this a "box-ripper" and now I know why. I would highly recommend this to anyone that opens boxes. Just treat it like any other knife and keep it in a safe place away from children .

My old box cutter had seen better days so this one is a replacement to open the boxes that are delivered. So far it works fine.
