Ham-Wrench? Wrench-ham?
This is every builders’ dream. A tool to handle multiple purposes at once. Not just an ordinary tool, a device that functions with two completely different focuses. This person had the idea of combining a wrench with a hammer.

Now that is creativity in the making. Instead of going through the whole toolbox to search for a hammer or wrench or losing one another on the job, why not weld one to the other. Need nails to hammer and screws to tighten? Then this is the perfect tool for you.
