And the hip bone is connected to the mojo bone...
I've been researching handles/scales and came upon this:


Oosic: is the penile bone of the walrus. The bone is very strong and often large, and is easily obtainable. It has an outer hard shell that is nearly as dense as ivory, and takes a very fine polish. The smaller end of the oosic creates a fine hidden tang handle when left complete. There is considerable superstition and mojo attached to the oosic, as you can imagine. Although oosic is common, I've seen hyperinflated prices and "rarity" claimed. It can be carved, scrimshawed, and dyed. It fares better than stag, horn, and bone in longevity on the knife handle, but not as good as ivory.
