I enjoy to control the edge angle. This picture shows an edge with two different angles. The differance between those two angles is 1 hundred part of 1 degree ( 0,01 degree).

I first made the complete edge perfectly flat, then I changed the sharpening anglee with 1/100 part of 1 degree and made the next angle. I made the scratches diagonal in different directions so that it is possible to se what I did.

I use a Norton 20 mkcron diamond sharpener for this. The sharpener is 10 yeras old and have beennused a lot and are perfectl warn-in as you can se on the scratches.

In my mind itbis important to control the edge angle to get an edge as sharp you like to have the edge - in any levell of sharpness.

When I control the angle can I decide how I shall grind it, what grit/microns I shall use, if I like to have micro teath or not. This means that I can decide the edges sharpness. I understand and knows exactly what I shall do to reach the reslut I like to have.

If I like to polish the edge it is just a question of how I end the sharpening process and in what grit.

I have not tryed it, but I think it is possible to grind angles like this down to 0,005 degrees - if I go down to a 9 micron diamond sharpener.
