[Bill Harsey]

Checking for burr on the backside of blade with fingernail.
If no burr is perceived or felt this means not enough sharpening of the bevel has been done.

Do not change the angle of sharpening, just do some more of it and re-check until fine burr is felt.

What is not shown is visual check of any flat spots out to the point....
and there was so a bit more sharpening of the bevel needed to get done.
