i bought a strop and I got a white, and green compound with it. but I don't know much about them and how they work on high quality steel. Does anyone have a kind they prefer that will work well on a strop for touching up, or finishing off after honing? I have two knives one with CMP-S30V and ZDP-189 if that makes any difference for a compound to use. its also a 2 sided strop one side coarse the other fine. Any suggestions would help. Thanks
