It’s actually both. There is another piece of shaped antler in the other side. It serves as a leather wrap to keep the top of the sheath in place. I added the sleeve so the owner could attach a sling if he wanted.That's really nice! The piece that looks like a tooth. Is that just decoration or does it have a function that I don't see?
OP you did a fine job.
Because I grew up eating lutefisk I would love to take a good look at the ax.
