Answer to: How to remove pentalobe screws without correct screwdriver?Ive tried all the above suggestions to mixed results. Some absolutely sucked for me but one worked great but I used a different take on it. I took a glasses repair kit screwdriver that typically comes with new glasses or glasses wipes/spray. I had been ordering so many glasses online I had a pretty hefty stock of these tiny (though not tiny enough) drivers. I used a typical grinder bar and swiped the little flat-headed screwdriver on it for like 30-40 strokes until it was half the size tip it started with and it works flawlessly.
