If you cut them with a torch you would lose the temper on the metal and make it soft. did you hardface em after cutting and regrinding?Angus Cowman":detnvbmn said:I sharpen mine atleast 5 or 6 times a yr
if I am cutting brush I want them dull but if I am clipping pastures I want them sharp
I have even had to take a torch and re-bevel them if they were really bad then sharpened the edge
was alot easier and faster than trying to grind the bevel back into them
All of the blades I have ever seen are soft or else they would shatter when you hit something that is one of the reasons the edges will wear down and become blunt if they were tempered they would shatter when hitting something solidMasseyFerg":eyltsjob said:If you cut them with a torch you would lose the temper on the metal and make it soft. did you hardface em after cutting and regrinding?Angus Cowman":eyltsjob said:I sharpen mine atleast 5 or 6 times a yr

My old Uncle told me that when the blades get sharpened until they can't be sharpened again cut the cutting edge back about 1 1/2" and weld on a piece of grader blade, the part that gets replaced. He tells me the metal is much tougher and the sharpness will last much longer.
