Make a seperate class that extends Item, e.g. MyItem and then use that when registering your item instead of using the Item class: public static final RegistryObject<Item> pounder = ItemInit.ITEMS.register("pounder", () -> new MyItem(new Item.Properties().group(ItemGroup.TOOLS).maxStackSize(1).setNoRepair().maxDamage(63)));
