I'm having the same issue as PyroSalamander on your comments page - it does not matter which schematic I put in the crafting bench, I can make a shovel, hoe, pickaxe, mace or hammer head, just depending on the number of crafting grid slots that are occupied with a material. The arrangement of materials makes no difference, meaning I can't craft any kind of axe. I tried spawing in fresh schematics but still have the same problem. We've been able to replicate the issue on multiple minecraft installs. We're testing this as a lightweight alternative to Tinkers for our modpack, and apart from the above bug like it very much, especially the compatibility with other mod's metals. Keep up the good work!

I haven't been able to replicate this. Maybe try updating your forge version?
