Answer to: Pentalobe screws bottom caseI bought a cheap set of assorted screw bits, at Harbor Freight that included about 30~32 different oddball shapes, and sizes. I don't know the various names they might go by, but among them are star shapes that include 5 and 6 point star patterns. plus more standard phillips/flat, square, and 'H' tips. Since they are a smaller diam. shank than the typical screw tips suited to household or construction screw driver ratchet or screw guns a adequate handle is also inside. I paid probably $5-7, but certainly less than any other similar tool sets available from all the other tool vendors. Safe to say these are poor quality, but snap-on or high price tools of trade professionals, are certainly not needed for such lightweight gadget work. As a rule, I only buy Harbor Freight junk when it's feasable to know my purchase doesn't need to last a lifetime, just long enough to do a task I don't expect to ever take on again!
