Crude Bone Axe - Assassin's Creed Valhalla Fan art

When I was browsing the "Art of Assassin's Creed Valhalla", I came across a pretty interesting weapon, that made me wonder If I could pull it of. So here Is It, I hope you'll enjoy It ! I'm not sure which artist made It. But It's on the page of Jose Maria, Lorenzo Gomos II and Tey Bartolome.
