Steel (i just mild steel from the hardware store)
Bench Belt Sander ( A file works too)
Pencil,Sharpie, Pen, Soapstone (any)
Clamps, vice, etc.
Step 1: Design and Plan
i went with a very simplistic shape but the possibilities are endless. i recommend nothing to far stay in your skill level. A symmetrical knife is better but not required. FYI larger knife are much easier to throw trust me!
You can make a cardboard template but i just marked right on the steel. i used a piece of soapstone because it stays on even with heat.
