I'm custom builiding myself a Destiny comabt knife

I am starting with a Frost Cutlery Combat Fighter knife, not a very high quality tool, but it's going to be for looks. (and the one I own has held up well through moderate use, so I'm confident it will survive a little drill-pressing) Obviously the faux wood handle has got to go, or at least be painted. I'll be stripping most of the blackening off. Drilling some small aesthetic holes near the upper-middle of the blade. And I'm toying with the idea of adding serration to the back edge. (I live in a state where double edged blades are legal) Any further suggestions? (specifically, what to do about that archaic hilt, it's rather ugly)
