These aren't anything special or new, but I am rather proud of them none the less.
Finding claw models that are CC0 is near impossible. Thank you so much for posting this. I've created a modified version of this for unity that has realistic wood textures and swappable metal material claws. I've included the modified asset in the AnyRPG Engine. Its been featured in a YouTube livestream at https://youtu.be/t4xqkYE9YrU and you've been added to both the in-engine credits, and the credits at anyrpg.org.
