flint axe from no tree punching into rust rock

I made a rock resource pack for the No Tree Punching mod because I wanted the early-game tools to look more realistic and fit better with the survival experience. Since the mod makes players start by using rocks and primitive materials before getting normal tools, I wanted the rock-based axe to have a more natural, rugged appearance. The resource pack gives the axe a rough stone-and-wood design, making it feel like something a player could realistically create at the beginning of the game.
