Cigarette paper test - slice the edge furthest from fingers holding the cigarette paper, then push-cut down.
Becomes possible at 30 BESS or 0.06 micron edge, but cleanly performs only at 20 BESS or 0.04 micron edge.
This one is a highly precise test due to standardized "test media", and I replaced with it the toilet paper test in the sharpness chart on our website Sharpness Chart >>
I never took that single ply toilet paper or facial tissue tests seriously anyway.
