Non-Marring Hammer for Woodworking?

I spotted this tiny non-marring hammer over at a recent Woodworking show. With dime-sized replaceable brass and plastic heads, this hammer is most likely used for precision tool setup or maintenance, unless there are other woodworking applications that I’m not yet aware of.

If you look carefully, you can see another small brass hammer that is hidden by plane shavings.

Can you think of any other ways in which these hammers could be of use to a woodworker in a non-power tool setting? If it makes a difference, the hammer faces were very small, about the size of a US dime in diameter.

At the show, the hammers were on a workbench amongst mallets, shavers, and planes.
