Boxer cutter key ring

thingiverse

I designed this tool one day after getting locked out of my house because I bent my keys trying to open eBay packages. It's super handy since knives are not allowed at work, where I'm often stuck dealing with stubborn packing tape. Travelers will also appreciate its usefulness when navigating tight airport security restrictions. Printing it in PLA, Nylon or Polycarbonate ensures a sturdy build that can withstand the rigors of breaking through tough packing tape.
