Dang Doc, You should know that baleen isn't bone at all. Keratin, not unlike a horses hoof or a buffalo's horn. How'd it smell when you were shaping it? Of course I'm sure the old sailors weren't to picky when they were trying to figure out what to call it.
You should call that line of knives "The Mysticeti". Mysticeti being a baleen bearing whale.
As always, great looking stuff!
