To start, Estwing hammers, through the years haven't changed much because they don't have to. I'm 72 and I still have my 20 oz. Blue handle smooth framing hammer purchased in ‘67. I now have 7 different types of Estwing blues to go with my first leather, straight claw, just purchased. What a beauty! At this point I can't speak to it's toughness, but again, it's been around a while in Estwing's lineup-says a lot. I can say that this hammer feels good in the hand and is properly weight balanced for efficient nailing and ease of effort.
