Ron's suggestion of using Sentry Solutions TufCloth is the best way I've found to keep bead blasted finishes in good shape.
The Benchmade 975, which is probably what you have, was designed by Emerson. It was also the first one made and it's largely responsible for the CQC following. Emerson ended his relationship with Benchmade a few years back and opened his open business.
I have one that goes on canoe trips regularly. Which means, with my grace, it gets dunked at least once a day. It's survived 1½ years of monthly trips with no discoloration, rust, or staining. I do dry it off at the end of the day and wipe it down with a TufCloth. I also use the TufCloth after the blade is fouled by staining things like animal blood.
If it was around salt water, I'd go to the Sentry Solutions Marine TufCloth. It leaves a heavier coating and has been used by some elite armed services.
If you want to keep the bead blast, I'm sure someone around BF, if not Benchmade, could do it.
If a satin finish would be ok, go to a local paint store and buy some 3M Scotch-Brite Hand Pads:
#7447, maroon, 360-400 grit equivalent
#7448, gray, 800-1000 grit equivalent
If you'd rather have a mirror finish, after using the maroon and gray, then use
#7445, white, 1200-1500 qrit equivalent
It'll take some elbow work, but these really do work great. I belive Spyderco uses an industrial version on their knives.
Good luck!
