Thanks for all the insight guys, I was hesitant to make this post but curiosity was getting the better of me. As I stated in my original post I saw the Hand American web site ad stating that his leather belts were suitable for use on knives and straight razors. He even shows a picture of someone stropping a knive on a belt sander fitted with a leather belt. In the ad he states that you can strop a straight razor for a few seconds with out doing harm. Not being an expert I was thinking of ways to emulate the final stropping a razor goes through at a factory. Things like blade temp. and the speed at which the leather belt might be traveling on the machine are important factors that had not occurred to me. I guess I was just looking for that little extra something. I can get my razors pretty sharp but consistency has been an issue for me. Thanks again to all that replied.
