A prybar or crow bar is wiggled genly when used to dismantle most trim or woodwork...So is a frying pan...or a metal pot or pan while making popcorn...I wiggle a metal wedge into wood for splitting, or a chisle to carve...I might even wiggle a rasp over a peice of wood to smooth an edge...I could even gently wiggle my metal mixer to create the perfect martini...etc. etc.
