In the future, it might be nice to let the perspective downloaders of your mod to know that they need the iron anvil to craft these weapons. I won't say I know anything about modding, but maybe ti would be easier to tie the recipes to the generic crafting table? That way those who have reached the end tier of crafting don't need to dig up something that they would rarely use otherwise. But other than that, the mod looks good. I'll be interested to watch for your improvements.
