Gained from lions, raptors, clawmonkeys, and eagles, claws are crafting components and cheap ammunition for the slingshot and the arbalest. Into the late-game, creating clawspears with the claws over regular spears can be a top choice, due to the fact that many of the creatures you'll be hunting are hostile and will drop their own claws, making it a net gain and also safer.
Claws are ammunition for the slingshot and arbalest, making them only viable in the very early and later stages of the game due to the weak power of the slingshot and the high power of the arbalest.
Claws do 10 damage alone, but on top of the 1 damage of the slingshot they do a total of 11 damage when fired from the slingshot. When combined with the 1 damage of the arbalest, they do a total of 11 damage when fired from it.
