I had my first vintage strop this weekend, via my box of razors i was lucky enough to get, its a roma, and has a seprate linen strop on the back, well during cleaning it up the strop came apart at both the hanging end, and the holding end, thats no problem as i can sort that out as the strop/linen is undamaged, just the leather wrap around just sort of perished, so i got the linen side cleaned up, and also finished cleaning the leather side up and it looks good, but what i did notice was, that the back of the leather strop is exactly the same as the side that has been used, but for the reason its been unused, in perfect condition, the used side of the strop is also very usable, but seeing that the back has been unused i was wondering if its possible to use this side when i put it back together, or shall i stick to the proven used side?
