there's supposed to be some kind of tights belt to restrain that, wtf

@dantsypants I was wondering. Otherwise this would happen more often.

The best suggestion I've heard for opening these: can opener. It actually works and takes off that sealed edge. Unless you have an internal corner...

or a pair of scissors.

@delf Like, a manual can opener? I can see running the little circular blade along these.

Yep exactly @cow
