First, just polish it up by sanding with wet/dry paper up to 1500 or whatever. Wipe on a thin coat of shellac and let it dry. Then take a scrap of muslin or similar fine cotton cloth and wad it up into a little pad. Put a couple drops of alcohol on it (just barely damp) and rub the surface with hard and fast circular motions. Shines up real good, by slightly softening the shellac surface and burnishing it out. And no risk of trapping buffing compound in pores
You could also pumice fill before the rub down, and/or French polish up a thicker shellac layer than the initial wipe, but I think cocobolo would look just fine with open pores and the simple rubbed sealer.
