What a contribution it was. And it adds to the character, knowing that this power comes at a price. Thank you for sharing.

FYI: checking something else I noticed in X-Men #150, roughly a year after JB left the title, Wolverine was in a place where mutant powers were turned off and he used his claws with Scott mentioning how his claws were not part of his mutant abilities.  IE: even post-Byrne they were mechanical until someone decided bone claws would be cool. 

About the bone claws...

I remember the reveal he had those happening after the story where Magneto ripped the adamantium from Wolverines bones in the 1990s. I also remember Peter David said he was jokingly asking why Magneto hadn't just ripped the metal from Wolverine's bones during a X-staff meeting, and being surprised when the others at the meeting were excited with the idea. This storyline also led to the horrible "no nose"/more savage monster version of Wolverine, as apparently it was the adamantium that kept Wolverine from mutating further than he had.

Oh, and I found this other info online:

"...The original plan for adamantium did not make sense because Wolverine's bone structure would not be maintained if they were literally removed and replaced with pieces of adamantium metal. However, people also began to note over the years that even coating his bones in adamantium would be too much, as bones need to get oxygen to work; if they are coated in metal, they would not be receiving oxygen, and that would be very bad, even for a guy like Wolverine.

Thus, a few different facts were revealed in subsequent issues during Larry Hama's run on Wolverine. Hama famously doesn't plot that much of his stories out ahead of time, so someone must have just told him about this issue before he started writing Wolverine. Rather than coating the skeleton with adamantium, the adamantium was revealed to have bonded with the bones to form a new sort of substance that was different than just metal-covered bone. Secondly, this new substance was revealed to be a new form of adamantium, known as beta adamantium. Beta adamantium allowed for bones to breathe like they would in nature while still having the other properties of adamantium, such as the practically indestructible nature of the metal. Pretty neat fix, huh?..."

Um. Okay? Whatever.
