I added a few videos to my You Tube channel. They show the actual process of hardening the edge, by heating the edge with an O/A torch and quenching in oil. These blades are flat ground, and pretty thin, so it doesn't take long at all to heat the edge with a large welding tip adjusted to a quiet carburizing flame.
This is a normal example of a full size hunting blade;

This is the result. You can see that a little of the light scale has popped off, maybe 1/4 to 1/3 of the way up the blade from the edge. This is just right, because more of the edge will actually be hard, as you will see after the blade has been etched.
