Here is the work I have done on my only straight razor, not to make it shave ready, I don't even know if it is wide enough to do so, but as it hadn't been used for at least 40 years it was oxidised turning blue. Hope you like the photos and the procedure! As I didn't have any electric tools I did all the job by hand and wet sanding with 80-320-400-600-1000-1500-2000-2500 water sandpaper and a paolishing compound in the end. Enjoy!
