I just completed disassembly. It isn't necessary to cut into the seam. Instead, use the blade of a putty knife as a lever. Insert the putty knife into the seam/groove, and gently pry the two halves away from each other. You'll hear the glue start to crack with little or no damage to the plastic. Repeat all the way around. It may be necessary to use a second putty knife, or a thicker similar tool, as the gap begins to widen. Just keep prying in this way until the two peices are free. Don't use a screwdriver... It will just ding the plastic. Also be sure to cut the label on the bottom first (a razor blade or exacto knife makes a nice clean cut).
