Sorry Timmy, your comment was about people not liking mirrored edges because they lack ability to get them easily. There was never a question on how to get them on the cheap. You are not the first person to use a block of wood and sandpaper.
I know a thing or two about sharpening so yeah.
Actually the last and longest post I quoted complains about the $$$ involved in mirrored edges. So yes there was a question of cost that I was referring to.
