A new edge for a custom Demko

User custom Andrew Demko in CPM-M4 high speed steel from a Dutch forum member

Before sharpening:

After sharpening.
Reprofiled from +/- 30 degrees inclusive to 25 degrees inclusive on a standard Paper Wheel with 220 grit SiC, then refined with a second Paper Wheel coated with 15 micron diamond compound, and finally deburred with a third Paper Wheel coated with 1 micron diamond compound (experimental)
The new edge survives a few forceful test cuts into my laminated test block without any visible damage (seen through a loupe), after which it effortlessly treetops the hairs on the back of my hand and slices single-ply toilet paper.

Length closed: 5.3 inch (13,4 cm)
Blade length: 3.5 inch (8,9 cm)
Blade thickness: 4,57 mm
Steel: CPM-M4
Lock type: Tri-Ad lock
Handle material: Tan G-10 on titanium liners
Weight: 214 grams

I don't think the holes in the guard are something like a safety lock the RAO uses, there are also no threads in them.
The owner uses the knife just as it is, and with it's incredibly strong lock i also think there is no need for anything else.
He was pleased with the new edge by the way
