yes, how it was broken is a good question, I looked at it a few times and sked myself the same question. the other side looks so good.
I have never seen one crack like that, they are a solid wrench.
I had seen another brand that the guy put a pipe on the handle, and the handle cracked first,
not the jaws.
in the past, I was guilty of hitting adjustables with a hammer, the same thing with wrenches.
it's good that it will be listed for a while, I have learned the hard way about putting an item
on ebay when there is already one for sale.
