What is your sharpness test?

[SpikeC]

I always use a strong light source to monitor my progress as well as the ongoing condition of the edge.

Does nobody use the sun (or reflection of sunlight) to see if you have burr or not?

Of course. I don't know that I'd really call it a "sharpness test."

C'mon tk, you know that one of your tests is to cut photons in half...then it's almost sharp enough for you...

To Dr. Naka:
Yes I do, but only at the 1k level to make sure the burr is built up evenly and any chipping or uneven grinding is worked out. If I still see light reflecting off the edge after deburring off a 1k, I am not done on the 1k. After that, I don't see any reflected light at all...If I do, I built up too big a burr or hit it against the granite counter when reaching for a beer.
