Thanks. It is nice victor. Did you polish with the blade in the handle, a jig...? Did you go up in 200grit increments? Finally, what types of polishing compound did you use? Thanks again!
Lots of advantages using jig/fixture. I made a simple jig out of left over spacer T6 material, drilled and tapped for 1/4-20 thread. But you can make it any which way to suite you! I went out to take this picture to show what is being work on:

Combination of pivot-able blade mount and flat jig allow blade to work on different position without body contortion, better able to maintain my natural body positioning mechanic comfort for a sharper definition on blade finish. Here shown I am set up for mirror polishing progression:

I started one grit more aggressive then the guesstimated original finish under the tested stone wash, to ensure I ended up with a positive base line. Other than jumped 1200 to 1500 and to 2000, the rest is 200 grit increments. For lubricant, a few drops of dish washing soap + water will suffice.
In regards to polishing compound - I used diamond lap compound, stepped from 14, 10, 6, 5, 3.5, 1 and .5u to achieved the posted mirror. Transformation from 2000 grit dirty mirror to clear is immediate and improves with progression. For me, always a very satisfying experience.
Caution: Insingo is not a flat grind. I made several tubular tools using left over lexan tubing, machined T6 round tube and such, slit side to hold emery for better conformation to blade contour. Nothing fancy, really! If you need picture to clarify, let me know.
HTHs!
Aloha!
