churchkey

[Hog On Ice]

a type of tool used to cut triangular openings into cans - has a small tab that hooks on the edge/seam of the can then a pointed triangle that pierces the can and cuts the triangular opening.

usage is believed to derive from the use of steel cans to hold beer in the days before aluminum tops/cans - having a beer on Sunday required the use of the churchkey.
