Ironwood is beautiful but a bear to work with, plus the sawdust is toxic. But, although it would probably wear out a couple of sets of checkering cutters, a finished set of ironwood grips would be hard to beat. I have some ironwood that has been lying around in the garage for years waiting for me to turn it into grips. Not for a Luger though, they will go on a single-action .45...someday.
