After you anneal and grind out your blade, you will need to get it back that hot for the hardening process. There are gobs of cheap forge ideas on the web. Try that famous video web site for some ideas. I would also search this forum for buildalongs for knives from files- that's how I started with only charcoal, hair dryer, magnet, belt sander in a vise, files, sandpaper and transmission fluid.
