What I learned from crafting in TF2:
1. Boots are made of shields.
2. Pour energy drinks on a sandwich to turn it into chocolate.
3. Sledgehammers are made of swords and pickaxes.
4. All weapons require at least 3 small piles of polished metal.
5. You don't need any tools to make objects, just put them in a box.
6. When recycling old "used up" metal, you put three of piles of it in a box.
7. Hats are always made out of metal. Most of the hats have stickers on them that looks like fabric.
8. Putting two hats in a box will ALWAYS make a new hat.

Anyways, I've been waiting a long time for something like this.
