I've been trying to open the head on this 1AA flashlight casually for a while now. I finally got serious tonight and boiled it for about 10 minutes. STILL won't open. The space in the pill for a tool is so small, I can barely get anything in there and it slips out before i can get too much pressure on it. I stopped before i messed anything up (beyond a scratch or two on the inside), but i still want to get it open. Anyone have any tricks?
