Hi all, A friend literally dug up this hammer here in Hilo HI, an area with no industrial or metalworking history, and we're perplexed as to it's use. I got some guesses on an antique forum but someone suggested a blacksmithing forum, so I'm asking you guys if anyone has seen anything like this. It appears the larger hole was for the handle and the smaller one is what has us wondering. It's cast into the head, is as big as the handle hole on the surfaces, and tapers down to about 3/8". I'm guessing maybe a rope or wire was threaded through it for some reason. Thank you for any opinions. Ricka
