No offense, but actually you would get the steel hot enough that it no longer sticks to a magnet and then quench it in oil, then being very carful (the metal at this point is very brittle) you bring it up to about 500 degrees for an hour or so and let It cool, this hardens and tempers the metal to be not so brittle but just as hard and sharp
None taken! As I said, I figured someone with more practical heat treatment experience would know better. Thanks for the correction!
I made a realy nice we'll balanced 6 point shuriken, from a piece of hot rolled 14 gauge mild steel I got from a metal store it was about 48" by 48" and cost me just under $10
