-''PotatoToolMaterial'' can now be referenced with ''PotatoToolMaterial.INSTANCE''.+''PotatoToolMaterial'' can now be referenced with ''PotatoToolMaterial.INSTANCE''. Alternatively, you can implement an enum similar to vanilla's ''ToolMaterials'' class that implements ''ToolMaterial'', which provides the instance and also allows easy creation of multiple tool materials.
