Here is a dude that got a 14mm wrench stuck on his. That’s 9/16” in case you are scoring along at home.

Best I have ever done is cut a bearing race off of a guys finger with a Dremel.

George, I said get a wench! And 14mm?

Depending on the circumstances, I wouldn’t look forward to trying it. I have a lot of respect for your apparently steady hand if you successfully did it.

Probably a 6 point box wrench.
