This is a counterfeit Estwing hammer. You can see in the photos I took of the hammer I received versus the Eswing hammer. The estwing hammer bears the estwing mark and a patent number. Warning, this is false advertising. They advertise the Eswing in the picture and that it's made in the USA, but I highly doubt it. I would have gone back but I had already made the grooves for the towers before realizing I had been scammed.
