When people come by to try out my hand planes this is one of the things I try to show them about sharpening.Quote:
I look at the edge with a bright light source from overhead.
If I can see light glinting on the edge, that's a flat spot.

Calloused?
When I demonstrate joints, etc and stop to sharpen a blade, I pass it to the audience and ask if they can feel the wire edge off a 12000 Shapton. Rarely can they. And neither can they get a 5000 or even a 1000. Yet to me the wire edge is very noticeable. Perhaps it takes practice?
The other issue is that if you use a Ruler Trick, you will then struggle to find the wire edge as it is no longer co-planar with the back or the blade.
