[TheForge] need help on a project

If you have access to an induction heater in one of your friends shops, 
you could easily heat the edge with the handle in place and quench the 
edge without a problem. I have not used the 'heat a LARGE block of iron 
and heat the edge with that' method but I could see where that would 
work also... I can, however, tell you that the induction heater does 
work very well.
