After tempering I am back at the grinder to bring the blade to final dimensions. I am trying a technique that I saw on a flat grinding video where the oldtimer always flat grinds from the same side of the grinder. I am using a 60 grit belt here.
The technique seems to work okay. I gauge the angle by how far the spine is away from the belt, say 1/8".
I've ground down to close to 20 thousandths. Enough to work the final cutting edge from there.
Some light scratch removal with a 120 grit.
And hand sanding up to 400. Once in 400, I draw the paper across the blade only in strokes one direction.
