Rant: I used to think a 2 lb hammer was fine for everything, but a 1.5 lb changed my whole game.
I was shaping a shoe for a big draft horse in Kentucky last month and my arm was dead after an hour with the heavier hammer. Switched to the 1.5 lb for the next shoe and had way more control for the nail holes. Is the lighter hammer just better for precision work, or am I missing something with the heavier one?
