Funky new hc:
Skullkin bones are solid. Because they don't have blood they have no need for bone marrow, so their bones are just hard all they way. Additionally thehre very sturdy and much harder to break than normal human bones because that's literally all they have. This means that Skullkin bones make great tools! They can be carved into the needed shape and they're pretty durable, maybe chipping a little but still solid.
Anyway give the legos knives made out of bones please it would be funny
