This thread is feedback on feedback about feedback. The information you get from input. If I put too much pressure on a blade going across the hone I get negative feedback. If I do it right I get positive feedback. Smooth is the feedback I am looking for and anything that eventually gets me there is the feedback I try to repeat. If I feel a bump there is a hair or grain on the stone and it needs to be cleaned. If I hear scratching it should decrease as I continue with laps. Anything short of that is telling me something is wrong.
