I am absolutely disagree who says edge gets it is sharpness on 1k level 4k level.
REST is POLISHING?
Can a good Person explain to me what does polishing do? or meaning of it?
Does it changes thickness of the edge?
or just makes shiny bevel?
My opinion doesn't matter how you guys call darn edge gets sharper as you go all-way (1k,2k,5k,10k, so on)until the end depends where you stop.
