If it were mine I might send it in for a sharpening, as the blade looks rough out to the tip, but would leave the handles and hardware as they are. Knives need a good cutting edge, and I have always been happy with the factory job. Those handles are functionally perfect, it is just some cosmetic imperfections, and I think some good ol wear fits the knife well. Plus, if you get new washers you could need to go through another break in period. Which is not bad. But the knife you have is well worn in.
If I also had a problem jumping out of perfectly good airplanes I might look into getting a serrated blade from CRK. Their serrations are nice, as they are not full blade length, but would come in handy if you ever needed to cut through some nylon webbing or something quickly and happen to neglect your edge.
Overall you did very well, but what do I know? I was just a leg. ;-)
Look forward to seeing some badass photos from your sky people. Take care.
