You are right, Mr. Mark. Aluminum conducts heat way better than stainless steel. You know, they make heat-sinks out of the stuff. As far as common metals go, stainless steel is a rather poor conductor of heat. I suspect what this means is that when grinding heat is not readily lost to the cooler body of the blade.
