I have seen some butcher knives(new) that appear to have the makers name on the side of the blade, is there a good way aside from grinding to get this off, maybe in a process to age, patina, or giving that crusty almost case colored appearance, any suggestions? I believe they are Russel, I don't want lettering to be visable but don't want to put in the asame time it takes to make a new knife to remove the preint, TIA
