I suppose I have never used a microscope as the use of them would only be confusing to me. I do what I know works.
With exception of damage to the edge, a properly honed and properly-stropped quality blade will continue almost indefinitely with proper stropping on fabric/leather and will get better and better as doing so. All I know. All I care about. Note 'Proper'!
Using pastes and abrasives in the mix? Up to you!
