My ZT 0121 Blade Grind

[Will B Hard]

The DLC coating on my 0121 was a little scratched, so i decided to send the blade to John Miller @ BJM. I am very impressed by this guys skills.
I have attached a before and after picture

Cerakote?

I'm a little confused by the thread title - did he also do something to the grind?
