I recently came across a glitch while trying to repair a kit pickaxe. As some of you know, you are able to repair enchanted tools and keep the enchantments by putting it into an anvil with another corresponding tool of the same material. Well, if you do this with a kit item, it automatically changes the name, letting you put it in the anvil again and change the name to whatever you want, making it look as if it's just an enchanted tool, and not a kit item.
