Hey this is a knife I made out of a piece of a metal fire pit grate I will be making more updates and will add more as i have time, enjoy.
Step 1: Metal
Basically for a no forge knife you need some already flat but durable metal such as lawnmower blades then you need to flatten any curves in the metal (see image above).
Step 2: Shaping and the Edge
Shaping the knife is the longest part, this calls for patience and a grinding wheel, shape the blade to your liking and keep a bucket of water around for cooling the metal. To put a edge on it angle the blade and grind it then sand any roughness off.
Step 3: Removing Rust
Removing any rust is essential, repeated sandings will do the trick, when then rust collects remove it with water and dry it with a rag.
Step 4: Handle
I will add instructions in the next update sorry, :(
Thats it I will add more when I can,:D.
