I have read through this thread and can share that my shaving with a single edge came about with ingrown hair issues using multiple edged contraptions.

Recently, I had a razor which would shave, yet not well. I tried and stropped and tried for 3 shaves. Back to the hones..
The results of trying to make it shave great when it would not resulted in some ingrown hair issues as I was 'short-stoking' it to get a decent shave, sort of emulating the multi-blades, as it were. Dug them out, Neosporin, shaved with the rotation, carefully.

A week later, all was well again. JME
