Cutting Edge (Micro bevel): 15k Shapton Pro Stone - 4 x light strokes per side.
With a precision instrument like the EP, irregularities quickly show on the grindline as either dips or mounds - I am happy to report that this blade presented none, which is extremely rare for a custom maker - well done there.
The heat treat felt very consistent with a slight "hard spot" at the heel, which bodes good, as this is where normally first contact is made when attempting the cut, resulting in a slighter longer lasting edge.
Slight "differential" HT in maker's favor.
I am happy with the final result, but for now, my fingers hurt!
