Darren, that is only half the process. After that hardening you must temper or your steel will be highly susceptible to shattering. I destroyed an antique knife blade by not knowing that. I accidentally tapped the hardened blade against a vice and it shattered like glass. There are different techniques. Re heating then burying in ashes overnight is one way.
