I've mentioned elsewhere that a wrench is a symbol of the clerical office. Here's what such a wrench looks like. The rings on the handle are to allow it to be held in the tail. It's as much a practical tool as a badge of office.

The wrench is quite heavy. Rumors say the weight is so it can be used as a self defense weapon, just in case the cleric gets accosted by highwaymen while working on transmission lines in the middle of nowhere.

Edit:

I literally just posted this and I realize the rings on the handle would get in the way. A better solution would be to have holes punched INTO the handle itself. Oh well.
