With some wet & dry SiC paper it would be relatively easy to restore the original full convex grind, and the knife would cut a whole lot better without a secondary bevel.
Yes, mine does have jimping on the spine, but it was worn very shallow/smooth so i recut each "jimp" with a small diamond file, and now it is actually useful again.
The hollow strip on each side of the blade is what i call an "aesthetic fuller".
Very useful on swords and such, but on short blades like this one it's just for looks.
The blade has been refined through grit 800 and 1000 wet & dry (again using WD40 on the piece of conveyor belt), removed the very fine burr on the Tormek leather wheel, and the apex can now whittle one of my chest hairs from root-to-tip at about 3.0 centimeters from the point of holding.
Also polished the aluminium pommel a bit on a felt wheel, recut the swedge with a small diamond file, and next step is to refine the swedge surfaces a bit more.
This is how the knife currently looks:
