I've seen several threads where corking a razor was mentioned. What does that mean? and why do it?
You cork the blade to dull it down a bit, usually not done with DE blades... sometimes done with feathers though... usually the Ted pella SE blades or some straights if they have had an edge made a bit to sharp
They take a cork and let it roll on table... and run the edge gently over it
My late wife always did that latter. She had me do the first couple of shaves with her razors to knock the edge off a bit before she would use them herself.Done to "buff" roughness from very sharp blades before the first shave, in theory making for a smoother shave. Another way, just shave and the second shave will be smoother than the first.
