We have a Wood handle wrench Vintage item.  It measures about 10" in L from the end of the wood handle to the end of the wrench.  The inner square within the circular end measures about 1/4" square.  The wooden handle is about 6" of the length on the tool.  The handle has some simple shapes/designs to it.  There is a split in the wood where it attaches tot he metal which is about 1 1/4" long, the tool is still solid.  It does have some overall wear showing, the metal is a bit rusty.
