To say that the knife was completely blunt would have been an understatement.
The request was to give the knife a new toothy edge with a lot of bite while making it as sharp as possible.

Before sharpening:
After sharpening
Flattened the acid damaged "apex" some more on a 3000 grit diamond plate so i could start with fresh steel, then made a new edge on a Rubber Wheel coated with +/- 230 grit diamond powder & wax, then deburred on a Paper Wheel with 1.0 micron diamond paste & oil.
The new edge is ever so slightly convex, the new apex fits almost exactly in the 30 degree inclusive slot of my Tormek WM200 Angle Master, plus it can whittle one of my chest hairs at about 5.5 centimeters from the point of holding. (i don't own a BESS tester)
The somewhat "fuzzy" shoulders of the new edge show how deep the acid has eaten away into the sides of the blade in some area's.
