[QUOTE="Smoky bandit, post: 407477, member: 7289"] Hi mate without going into detail this is a quick guide..Not all steel can be hardened..It needs to have some carbon content the more the better. Unfortunately mate you won't be able to reharden your shovel..You will more than likely just make it brittle :Y: Basic way is heat till red dip in cool water..Heat again till red then let cool slowly..Oil will give a black lusture to the metal.But I found water to harden the steel better as it cools quicker and that's what you want :Y: Good luck..
