A crescent wrench is 1: adjustable, and 2: always the wrong tool.

That there is a open-end wrench, or half a combination wrench.

(It could be a crow's foot but we'll leave that aside.)

In the rare instance an adjustable wrench is an appropriate tool, I'm partial to the Knipex "pliers wrench".

Most things that seem to call for a crescent wrench really want a pipe wrench or vice grips.
