wolverine's skeleton

So, if vibranium is clearly, in my opinion, the better material, why wasnt wolverin made with it. I mean, to my knowledge, there exists more vibranium. And it can clearly be crafted. So what's the deal?

adamantium has different properties such as higher overall durability.

For one they would have to go to wakanda and start a war and two. Vibranium seems to be a good absorber it wouldn't do that if It was covered by all that skin

vibranium is not as hard as adamantium.
