O.K. My turn to ask a question instead of answering them.

I just picked up an air hammer with a set of five chisels.

Looking at them, I see things which don't look right to me, but
since I've never used these, I don't know whether the problem is in my
expectations or in the actual chisel set that I got.

In particular, the two chisels which I would have thought would
be for ripping off old mufflers and such -- both sort of 'V' profile,
one symmetrical and the other with one wing shorter and thinner than the
other -- both have rounded corners, which strike me as difficult to get
started under the end of the muffler's clamp. I am tempted to go to the
grinder and sharpen them -- but before I do this, I would like to know
how they *really* are supposed to be used.

I guess that the rounded corner could be started in a drilled
hole for ripping sheet metal (body work). One is just a narrow cone
which would be nice for driving out taper pins or dowel pins. One is a
wide chisel with a groove in the center. And the final one is just a
plain chisel. Both of these last two do have somewhat of an edge,
though far from "scary sharp" (which I would hardly expect to survive
the first five cycles anyway). :-)

So -- Is there a good web site or book which will explain the
uses of these chisels, and how they should be sharpened? The extent of
the "manual" which came with the set was:

1) Always put a few drops of oil in the hose before using the
air hammer.

2) Always put the retaining spring on *before* connecting the
air hose or using it.

Absolutely nothing about the chisels other than "with a 5-chisel
set". :-)

At some point, I'll want to make rivet setting tools to go in
this, of course. And get a needle scaler for it as well.

For that matter -- do I need a cushioning glove to avoid damage
to my hand and wrist?

Thanks all,
DoN.
