Hi Frankie,
I often strop my knives on an old plain leather belt that I wear when hunting. I use the inside "rough" side of the leather and it works well.
I have heard of people "loading" a belt with fine abrasive to do a better job of stropping but I have not tried it yet. I think I read about it in the articles section in Outdoor Magazine
