Few weeks ago I was watching a video on you tube and this guy was using some chromium oxide paste(0.50 micron) on a nylon strop to maintain is edge. He was using the green paste, so I had the same paste at home and I went to a music store and bought a nylon guitar strap. I pasted my strop, let it dry a full day and gave it 15 laps on 1 of my straight who was starting to pull and tug. Clean the blade whit a tissue carfuly and strop it on my clean nylon(not pasted) 30 laps and finish up whit 60 on leather. To me for that razor it bring back the edge shave ready just like when a received the razor! Right now I did 12 shaves on the razor just by using my regular stroping routine I got very close, comfy nice shaves. Maybe the results could be different on my other razors but futur will tell. I kept a journal of # shaves I can get before I use the pasted strop again, but to my guess I think i’ll Probably good for at least 30 shaves. So to my conclusion every straight shavers who knows the technics how to shave and to strop should try it before puting a blade on a stone, of course it’s only my opinion and some already tried it and didn’t like it, but it deosn’t Cost much to try. Most important thing get some paste from some reputable straight shaving vendors.
