I have a HandAmerican flatbed leather strop about 8" long with one side lightly covered with CrO powder and the other side maroon leather with nothing on it. I got it for stropping knives and it does a great job at this, but I wonder if this would be good for stropping a razor? Should I ever use the CrO side or stick to the plain side? I have a good grasp of stropping fundamentals for knives but I've never stropped a razor before.
