Remove the handles.
Get some "Marine" grade paint stripper.
Lightly abrade the paint but not the metal; just some light scuffs with sand paper so the stripper can get UNDER the paint.
Keep the handles warmish; at least 70° F
Wait for the paint to blister; big soft blisters like when you get one from walking.
Brush off the paint with a scrub brush.
Reapply the stripper; probably need to do this at least once.
Pasivate the stripper when you get all the paint off according to the instructions on the container. This probably is just washing in soap and water and running a fine brush or pipe cleaner through all the screw holes and big holes in the handles.
The bare metal may not look like much when you are done. You will probably have to texture it or polish it and it is going to make black marks on your hands during hard use and or come off on your pocket. The aluminum will naturally develop a thin oxidized (clear) coating but it may not be even or durable.
I recommend replacing the scales with titanium. You will, as far as I know, have to make those your self. I plan to for mine.
Lets bring the Ti back into the Ti Lite
