So, I have a hanging strop that has 2 strips of wool (felt?), on 1 side I have .25 micron diamond spray and on the other I have chromium oxide .5 micron spray. My question is: when I use these to freshen a razor, or after a hone (in the learning process), is there 1 that I have to use before the other in order to achieve the best results or does it matter. I have tried it both way but I can't tell the difference, probably because I am still learning. I would appreciate reading what you guys have to say. Thanks a lot.
