I'm getting in way over my head but...

If we are talking about measuring microns in the thickness of an apex, Wouldnt a razor made of harder steel be able to have a thinner apex than a razor made of softer steel? Can't the harder steel be refined to even a thinner apex? But then we get into the foiling issue being so thin.

It sounds like we are splitting hairs, of hairs, of hairs here. lol.

Maybe I'm just thinking too hard.
