A trick that I have found useful in getting the muscle memory needed for good stropping is to put tape on a sharp blade or better yet use a dull blade and practice strop and roll on your pant leg when you have idle time. I still do this when I am driving since I usually have hours of just sitting in the cab of a big truck. I have even thought about making a paddle strop that I can strap to my leg so that I can strop raz9rs as I drive down the road.
