Review on Westcott Safety Knife (16475) with Slice Ceramic Blades by Derrick Feliciano

I wanted a small key tool to easily open boxes and packages. The currently popular metal door openers, even dubbed "corner box openers," don't work as well as my plain old decorative keychain that doesn't even have sharp edges, so I wanted something special for that. Plus: Can be hung on a keychain (maybe stitching a keychain together?) - not a metal blade, but a small blade. It can even pass the TSAI on boxes, envelopes and even snack bags. It works great on boxes and envelopes and not so well on slippery snack bags, but it's also difficult to accidentally cut your finger. The only thing I would prefer is to have more colors - I would like to have several different colors. and keep it in different places (in the car, at home, on the keychain)
