To me any hammer less than 8 lbs with a handle under 24 inches is a shop hammer, for me sledgehammers start at 12 lb with a 36 inch handle a small sledge might come in at 10 lbs
It is a cute hammer though would be nice for bumping things you don't want to put hammer marks on or for those times when you need non sparking

Cute hammer, nice foundry set up, and the hammer is pretty, but what does it have to do with pennies? Did you really melt down a bunch of pre 1982 pennies?
