I am begining to hollow grind my first blade and while I save up for a belt grinder I am using a bench grinder. Overall I doing okay at getting the right grind but I have left a couple areas that have discolored. Slightly brownish cast to the metal. I am grinding ATS 34 and wonder if the steel will be okay when I send it out for heat treating. I am cooling the blade and grinding slowly but near the edge is where the discoloring is occurring.
