It's already hardened so no need. Just use an angle grinder to grind a edge on the rasp and keep spraying it with water so it doesn't get hot.
I don't know how to properly harden steel so I didn't wanna lose the temper.
Also note that Anvil fire is an awesome site for learning how to work metal and a resource that I have used for years. The other guide is a Machinerys handbook that was published before ww2 as it still had blacksmithing information in it. I want to say 12th edition and earlier.
How I temper steel that I know is high carbon. Knives made from files, saw blades and rail spikes. I heat the entire piece in a forge until it is nonmagnetic. Then depending on the type of steel. ( anvilfire has charts ) either quench in used motor oil or a water borax solution.
After the metal is hardened and allowed to relax to room temprature I use either a toaster oven for small pieces or the oven in the house ( with water quenched steel) to bake it at about 550 to 600 degrees for 2+ hours.
When it is done baking turn off the oven and allow it to cool naturally and slowly. Either by sticking in a sand bucket or just letting the temp drop by turning off the oven.
That's supercool and I know it will work. Perfect metal for it.
At that time I did not believe it but after I tried it turned out to work. You've done it before ?
Yes but with a metal rasp. The easy thing about that is that it already has a handle :D
but must be burned for completion. it's probably the hardest thing I do.

I will read it looks interesting
I only use 1 tool. later I make a post about it. I invite you to see my post. thank you for sharing my experience with me
Will do, I am interested to see how you finish it out. and with that much saw steel left you can make a couple knives.
