A small mod which adds a simple custom crafting station. It changes the crafting recipes of metal tools from 'default' so that they require a tool head and a stick. The tool heads can be crafted at the anvil from thier respective metal ingots.
anvil: XXX OXO XOX X = 'default:stell_ingot'
You can use 'anvil.register_recipe(recipe)' to add your own recipes in the form recipe = { input = itemstack, output = itemstack, } itemstack should work for any of the three formats they come in.
