Westcott 17519 Full-Size Ceramic Blade Box Cutter, Retractable Utility Knife

Amazon left one of these in one of my shipments once (thank you for the freeby Amazon) so I tried it out. I ended up buying a few more. They work great. Light, small, very visible when you drop them in the yard (although blaze orange would be better) and because the blade retracts when you are not using it, it is much safer than a standard razor blade knife. The blade is rather small, but it is enough to cut cardboard, bags of mulch, etc. And no rusting.

We already had 1 before buying this. It works just as good as our original one. It's great for opening up packages!

Very safe and Excellent product. Shipping was super fast.

I use it daily and works great. Very well made.

This thing is a lifesaver! I have no idea how it works BETTER than the super sharp metal one I was using, but it does, and it’s lighter and doesn’t make me worry about accidentally hurting myself while using it.

I should have tested it before I threw away the package because when I went to use it, the blade wouldn't lock in place so you have to hold it to keep it out. And when I did, it wouldn't cut anything! Completely dull. I wound up using scissors. And threw this item in the garbage!

This knife is super lightweight and it has a safety blade that won’t cut you.

I have at least 5 of these scattered around to open boxes. They're safe because the blade automatically retracts when you let go of the button. Extremely sharp. Cut better and don't get dull like the metal blades.
