Line 12:
* What we're going to do
** Making a small utility knife
** I've made
** Show the metal, micarta, rivets, wood. Show the knife
** Describe the basic forging, making tang, drawing out blade, grind, harden, grind, handle, sharpen
** Legality, what we're doing is legal and why, what you can and can't do
* General Safety
** Clothing, overalls best, nothing flammable, avoid synthetics
** Heavy boots, toe-capped preferred
Line 32:
** Hazards of metals high in nickel, chrome, cadmium etc, and protection needed
** Arc-eye hazards of welding
* How steels behave and heat treatments
** Use the diagram to explain things
** The states the steel can be in, what is critical temperature and why it matters.
Line 48:
*** Maybe EN47 - +£5, TOUGH! OK sharpness, rusts, harder to work
*** Others I can get if you want to go further but don't have right now
* Welding onto the dop rods
** Anyone competent does their own, anyone else I do
** Emphasise use a LOT of weld material
Line 56:
*** DO NOT TRY TO CATCH THE HOT METAL
*** Pick it up IMMEDIATELY with grips, place onto hot-safe surface
* Lighting the forge [[File:Forgewarmingup.jpg|250px|thumb|Getting metal warmed up in the forge]]▼

** Describe the forge and it's parts
** How the tunnel can be opened longer for bigger objects
Line 75 ⟶ 74:
*** Large flames are more stable, small flames may result in burner over-heat, check this often
** Starting up the second burner if you have a need to for a long object
* Normalizing [[File:Forgehotmetal.jpg|250px|thumb|Normalizing the welds for the first time]]▼
▲[[File:Forgehotmetal.jpg|250px|thumb|Normalizing the welds for the first time]]
** Why we need to normalize
** What it does
** Proper procedure
** What happens if we're not hot enough, or too hot!
* Hammering technique
** Holding the hammer right
[[File:Forgehammering.jpg|250px|thumb|Hammering out the tang]]▼
** Aim from your arm, power from your shoulder
** Striking parallel, on the metal. You can tap the anvil but never strike it
▲* Flattening out the rod [[File:Forgehammering.jpg|250px|thumb|Hammering out the tang]]
** Heating to a suitable colour, testing with magnet if you need to
** Squaring it off but not all the way to the dop rod
