Hello Nortwoodsman, mate imo the best steel for you to use for this project is mild steel, simply because it's easy to work. To make a sword shaped object out of mild steel...not so easy, but a lot easier than a steel that JPH would use mate. Have a go at it, shouldn't take long, don't worry about the grind yet just get it straight first (don't mean to dishearten you here but straight enough is NOT straight.) When you do get it straight...ok that's enough, post a pic when you get it this far.
