luki's hammer

A mod that adds a single item - Hammer. By breaking cobblestone with it, you get gravel. By breaking gravel, you get sand - simple! Currently has only stone variant, but I will add more in the future. Supports JEI and can be customized with JSON recipes (datapacks and Crafttweaker or KubeJS).
Made with MCreator

DO NOT CHANGE THE TAG WITH HAMMER. It's there only for display in JEI
