The icon always looked like a footprint to me. It took me a long time to find out it was actually "Edit". I think the icon is mainly yellow to fit in with the add and remove icons, which are green and red (like the colors on a stop light).
I think that if you made a wrench icon with a yellow background and put it in the same spot, the current users would get it fairly quickly. New users would probably get it faster, which would be good.
