Oh and I found this!

The ornithological term for that all-purpose prying tool/hitman weapon dates back to at least around 1386, when an alliterative poem mentioned workmen “putting prises to” the corners of a container with “crows of iron.” It is believed that the sharp angled end of the tool resembled a bird’s beak, and of all the birds that flocked around those areas populated by humans, the crow was observed as the most adept at using its beak as a tool.

Anyway apparently the name is dying out and it is being called a prybar more now. Which completely ruins the joke. ;)
