I have bought three hammers from LV over the last 1/2 year and all of them have loose handles. Two Warrington pattern and one claw hammer. They must store them in very dry warehouse. I am mentioning it because I thought it was a norm nowadays, but just got a plane vanilla Grace brass hammer via Amazon and that one was tight. Grace brass hammer is nice btw.
I am sure I could just return them, but have not bothered to call LV and I already drilled hanging holes in the handles.
