check out the Bois du Commandant,

Well, you may find more results with "Bāton de commandement" (Command Staff) rather than Commander's Wood ^^
I read that those may have been tools for straightning shafts, but after a quick wikipedia reading, they seem to say it was like a "staff-amentum", like our fustibals, but for amentums...
