Just rebar, a rock, a hammer, hair dryer and a file.
This is dangerous, DO NOT attempt this without your parents and if you’re an adult make sure your affairs are in order – you are about to bite it!
It’s been pointed out in the comments and briefly in the video that rebar doesn’t make a good knife. But it’s a very cheap place to start with blacksmithing and good practice.
