I've worked commercial construction for 11 years and never seen anyone use any of the odd-shaped hammers like that estwing he linked to. The california framers like the vaughn are common.
A 14 oz. hammer? What do you use it for?
or you could buy a steel hammer and never worry about it breaking.
thats the downside to wood and fiberglas.
The Vaughn style are very common, but I have seen the other kind in use before. I've done construction and I was part of the carpenters union(although a Millwright) for 3 years. Hence the I wasn't allowed to own a claw hammer thing.
I'm wondering if Estwing has reengineered their hammers over the years?? I've used my hammer for hours at a time & have never had a problem with shock absorption.
