I've saved some cow bones so I can try to make flutes like these:
I attempted one from a goat bone two weeks but couldn't get it to whistle.
I also am going to use portions of them for guitar nuts and saddles. I know I can make guitars.
When I was a teenager, I used a big leg bone from a dog to make the handle of a knife. The blade was made from a ground-down file, then I carved the handle to fit and epoxied it together. It looked decent, though it wasn't a work of fine art.
