Here is how to forge a knife the easy way
Step 1: Remove all metal from your blade. This can be done by filing down the steel or using a grinder
Step 2: Clean the surface of your blade with a wire brush to remove any rust or debris from it. If you want to remove any scratches, you can use sandpaper for this step
Step 3: Apply a couple coats of oil or grease on your blade before heating it up so that it won't tarnish during forging process and make it easier for you to handle
Step 4: Heat up your knife with an open flame, preferably at a low temperature (around 350 degrees Fahrenheit) until its completely red hot, then move it into an anvil that has been heated in the same manner as well as some water in order to cool down quickly after forging process is done.
