What kind of screwdriver would I use for this type of screw and where would I get one?
I have a dysfunctional AA, AAA Rayovac battery charger that I want to dismantle for parts. I went to dismantle it when I noticed it has 3 strange-looking screws on the back holding it together, I attempted to use a small flat-head screwdriver to unscrew it but it didn't work. And I'd rather not try to break it apart as for fear of damaging any of charger's components. Here's an image of what the screws look like; sorry about the image quality, that is the best image I could get. So does anyone know what kind of screwdriver or other tool I'd need to dismantle this thing?
