Since my original posting another very interesting reply has come in
which I am posting below But there is one question which I don't think
has been mentioned and to which someone might have an answer.
------------------------------------------
The stone carvers use hammers the head being in the form of a truncated
cone (i.e. a wide cylinder with gently sloping sides).
So the surface coming into contact with the chisel is curved. One might
suppose that this would be more difficult to use than a hammer with a
flat surface

Thank you so much for posting the summary of replies to the Stone
Carvers
question. I don't think I've enjoyed a posting as much in ages! One
point
does strike me however - did nobody think to go out to the tool shed,
pick
up two or three different hammers and go and bang on some stone?
Perhaps researchers don't have access to a good selection of hammers
these
days but when I was a young child my father always had a plenty hammers
and
was very particular that I used the right tool for the job. And when it
came to large chucks of stone is was always a large heavy hammer with a
short handle. It was easier to control and striking the stone with this
hammer did not result in pieces flying everywhere - I was never given
(CE
marked) safety goggles and I never felt that I needed them. Even as a
six
or seven year-old I preferred the heavier hammer to the lighter pin
hammer
for chipping and shaping stone.
Anyway, keep up the good work - I look forward to seeing the results of
the
"humidity" posting (given that I'm now an ex-pat. living in Louisiana).
