The rough "grind"- file went real well ,I could keep nice flat bevels and work up to the lie, real crisp, flat and straight. Used the body file(magi-cut) first then the big mill bastard.
Then I went to the small mill bastard and started to draw file. I didn't draw file with the large file.
Drawing with the small file parrallel to the grind lines was too hard to keep the angle and I found out i needed some sort of magnification at this point to see the scratches and lines, had to slow way down. In the prosses I filed a dip in the top flat and there went a nice straight line.
So I think a Opti-visor is in order, the magnifier doesn't allow you to move to see at another angle which is essential.
I filed w/small bastard then sanded w/120 grit one bevel to see how it'd look, may have to go back to file.
I think the dark line in the bevel is a high spot, you can see it from any angle.
Anyway just thought I'd share my learning experience.
