How to create a File with Smithing
Files are an easy to make item with the Smithing Profession and are commonly used as an ingrendient in dozens of different recipes. One unique property of the File is it's never consumed in any of the recipes that it's used for, I have never even seen the File accidentally break either. You'll only need to make this tool a single time and you'll have it forever.
Once you're ready to make a File you will want to collect the following materials and visit a Forge:
