I have a high carbon blank that I am accumulating components to finish. It is a hidden tang blade and I plan to use chechen wood (aka chechem aka black poisonwood) for the handle. I have been searching for an appropriate material for a guard and pommel but so far have found few options. I have a bit of titanium and considered this as a guard but am concerned about the possibility it may promote rust on the non-stainless blade. Can anyone suggest suitable materials for pins, guard, and pommel?
