    Jan 02 2013 · only thing i know is carbide is like glass and if heated and cooled suddenly it can get micro cracks in it. this can cause an edge to break off. if a extremely small edge breaks off would this make edge tougher maybe if you were very lucky. i would say you got a 90 chance it would go the other way and it would make the cutting edge worse.
