I have a blade that feels very sharp, and also a little rough. My skin gets a bit irritated and red from it but it cuts hairs like there's not tomorrow. I drew it over my finger nail a couple times, and will give it a slight touch up on my slurry strop, canvas, and then leather. The idea I had is that any sharp metal "teeth" sticking out would be a bit more even. I'm trying to get a sharp and smooth edge. Do you guys know if there's any merit to this?
