Westcott Full Size Auto Retractable Ceramic Utility Box Cutter, Plastic, Green, 1-Count

I use this knife at work to cut open bags and a lot of them! Sometimes 200 a day and it's IV bags so it gets wet repeatedly and it still performs really well! This is a really good knife! It doesn't rust and never lets me down on sharpness!! Definitely recommend!!

So glad I bought this cutter! Excellent value for a ceramic safety blade cutter. The blade has a blunt tip and extends to approx. 1/2 inch - both protect against slicing into a package’s contents (or your fingers). Ceramic edge is more than sharp enough to whip through reenforced packing tape. I made a knotted lanyard from surveyor’s cord so I can hang the cutter from my wrist when dealing with multiple boxes. I didn’t realize this was auto-retracting - meaning you use the thumb slide to bring up the blade which then automatically retracts when you release the slide - I love this feature!!! You can pop it in pocket without worrying. A note: this does not have a feature to lock the blade in the up position.
