Just search the google machine and youtube. TONS of good info.
Some tips from my experience.
Really try and find out what kind of steel you have, will help alot. Get yourself some MAP gas, the stuff in the yellow bottle, if you do not have a cutting torch setup already. Try not to get the steel too hot when shaping it, I used my plasma to cut my blanks and this was too hot. I could give you a full step by step but there's a thousand of those out there already and you'll develop your own method as you go, if your first blade is a good one, then you are already better than most people. It is a bit tricky.
