Reality check

[grepper]

I have done no testing to verify this but I have a suspicion, a wild guess, that a toothy edge with a less sharp (duller) sharpness reading may perform better at some tasks than a smooth, very slightly rolled edge with a sharper sharpness test reading.

That would indeed be interesting to find out.  

It's why edge retention is puzzling to me, and what it really means and how exactly to test it.
