HIDI part 7; post heat treat and polishing

It was pretty cold in the shop; a good argument for pre-heating your oven!

I couldn't photograph the oven to quench process (only one set of hands). After quench, cryo, and temper check to make sure everything happened correctly
Just what I was looking for; 60.5 HRC
You can see I already started final grinding; remove the oxides and correct any grind issues.
A little hand sanding plunge line to tip to erase what is left of the spine to edge marks from the grinder.

Custom sanding blocks.

15 micron, 2000 and 2500 goes pretty fast.
If you did everything right you end up with these results.
