Thanks for the link!
We probably have 20 nylon and urethane hammers around here. I don't use them very much because they are very hard to control precisely. I know that doesn't look like precise work, but the work area was very tight and we needed the mass, impulse, and small physical size of a metal hammer to get in there.
You are right, they don't moon the metal like a steel hammer; but, then again, they don't move metal like a steel hammer either.
