So proposed progression will be this: 100/200 (shipped)
800/1000 (shipped) 1200/1600 Super Fine Ceramics (ordered, waiting) 1.4/.8 Micro Fine Ceramics (need to order) 5/3.5 Leather Strops (shipped) 1/.5 Leather Strops (need to order)
+1 to this and all other advice given here. If you get into judging how submicron stones/stropping compounds work, you may indeed consider to get a microscope. You are in the rabbit hole already .
