In S4E9, at 9’55”, Sisko is using it on various parts of his face. It almost looks like a shaver of some sort.

    That is for shaving his head. Geordi uses one in an episode of the next generation.

      I don’t think that’s Geordi. Geordi has hair. I think it’s Sisko.

      But yes, it’s a shaving thingy. (also known as a block of acrylic, lol.) Geordi also uses one, and Data asks why he doesn’t use the one he tuned to be “perfect”… and Geordi has to explain that too close a shave is uncomfortable.
