Ah.
Rolls Razor.
My godfather used to swear by the one he had. My father swore at the one he tried and sold it on after about a month.
Actually excellent devices if your bear is suitable but totally intolerant of poor sharpening technique. According to godfather you had to stick rigidly to the advised schedule and methods or the edge would become misshapen and no power on earth would restore it.
Factory recon services not being offered.
I imagine given a factory fresh example and a surface grinder a skilled craftsman might be able to bring an abused one back but the sharpening and honing system is geometry specific with only limited wear tolerance on the blade before it all goes wahooie shape. That said to my certain knowledge godfather got over 50 years out of his, it outlasted him, so they must have gotten something right.
Shaving is funny. In electric razor days Dad and I could get a good shave with Phillishave rotating head razors but not with a foil type (Remington et al). Brother got nowhere with a Philishave but Remington did just fine “I see why he bought the company.”.
20 odd years ago electric razors stopped working well for me so I had to go blade type. After some experimentation it turned out that Gillette Mach 3 and King of Shaves nostrum does the deed for over a month per blade shaving every other day.
