This is not part of sharpening, but kind of Quality Assurance. Actual hair whittling. This is my own hair, it is thin Russian hair. After Green Rouge I able to whittle it, but you need to go against hair shell, holding it at the end (hair looks like palm-tree).

After major polishing is done - 100 on each side, I focus on making edge even, to do passes changing sides. At this point I am trying to do this as gentle as possible, almost without pressure, carefully keeping position where very edge almost not touching the surface of the leather. This is final step.

This is final stage, so after I polished each side I even the edge by polishing it changing sides. At that point I a trying to do easyer then on previous steps, almost without any pressure.

After one 100 passes I change the side and do another 100 passes.

After Green rouge is warmed. I start polishing edge. Starting from the side on which I have burr from previous step - so I continue to hold handle in the left arm as on previous step because I change direction of moves. I can not rely on burr any more so I just do 100 passes on one side. Important not to round the edge - no too much pressure and keep knife the way the very edge almost near leather surface almost not touching it.

I am done with diamond stones. Now it is Green Rouge stage. I made myself sharpening device with leather stretched (not glued) to piece of wood. I cover leather with green rouge - chromium oxide to polish blade. But first I warm it under lamp and apply new layer of green rouge.

After forming burr - I wash stone and change side. Burr on Extra fine is smaller, because abrasive is about 9 microns vs 45 microns on Coarse and 120 micron on Extra Extra Coarse.

After position is set - I can do passes faster. Until burr is formed to switch to another stone...

After forming nice burr I change the side. I forgot to mention - I clean stone with water between changing sides. Diamonda take quite a bit of steel of - so it need to be cleaned often.

After Extra Extra Coarse I use DMT Coarse. Again same way - first find position and sharpen to nice burr all edge long.

After proper position is set, I just continue sharpening until I have burr on all edge length. Usually I do like 20 passes and check for burr.
