I do 50 leather 50 linen every shave but I rarely use the same razor twice in maybe weeks. I also do 10 laps on leather (horse) after the shave. I feel like it will pull any hair of skin out of the serrations that might lead to corrosion. I wipe the blade with an Outer's silicone gun cloth impregnated with RIG (rust inhibiting grease). Never have a problem with rust. (knocking on wood)
