Couple of years ago the Scottish American Military Society (SAMS) was considering designs for a kilt pin to include a bayonet, and several modern bayonet patterns were considered. The design finally chosen used a 17th century plug bayonet (the kind that fitted into the muzzle of a musket, obsoleted by the ring bayonet in the 18th century) in pewter. That was not my choice--I would have preferred a kabar knife design, but that probably would not have any appeal for Commonwealth customers.
