I've dug this out of the junk (to be sorted drawer), and while this is merely an example captured from the web, it approximates my 12oz version with some unreadable name on the head.
I'm finding no real use (carpenter or blacksmith oriented) to really want to hang onto it. The cross portion was sharpened to a chisel profile (vs rounded) so it might have been for whacking away at block, tile, or something.
How say ye? Are you a user of this style of hammer, or has it become just another display piece or relinquished to the special tools drawer just to have hanging around "just in case".
