Claws (Smithing and Bonecrafting)

[Pikaboo333]

The recepie is
Fire Crystal - Beetle Jaw+Steel Ingot

I know it caps out at 32 Smithing but, anyone know what bonecrafting is required for it and what bonecrafting level it caps out at? Many sights have conflicting info on what level of bonecrafting is required.

I think I recall a friend saying it stopped giving skillups when he hit 7 bonecraft.
