Slitter
Tough packaging opener thingy
 
Mounts on the bottom of upper kitchen cabinets and provides a safe, fast way to slice open the tops of those incredibly tough to open food and snack packages that are made out of mylar or kevlar or tyvek or whatever that stuff is that I can't get open.

You just slide the top of the bag through the opening and the shielded blade does its thing. Fingers are protected because the throat is much narrower than a finger.

Somewhat akin to those CD slicer thingies.
