Hi...Im testing with a norton 8k and a shapton 15k...
I was making some pyramids using both of them...
I lapped both with the same procedure, norton lapping stone, 600 sand paper, 800, 1000 and 2000.
while Im in the 8k, it feels smoooth....but in the 15k I heard like the razor on a wall....I hear the steel beeing removed from the razor, and see the darknes in the stone....
Is it normal? should I feel the shapton as smooth as the 8k norton?
I will test the razors maybe tomorrw
Regards,
