I got the Poor Man Strop from Strops | WhippedDog - https://www.whippeddog.com/strops. It came with chromium oxide and iron oxide pouches. I've been using one side of the strop (I think the non-suede side) for the past few months but it's no longer maintaining a sharp-enough edge. Is it a good idea to put the oxide on the other side of the strop? If it isn't a good idea, what do you suggest? From my research, the reviews are a bit mixed on this.
