Is this the reason they have switched to Pentalobe screw. I have googled for material but couldn't find anything. Pentalobe screws are not that hard to find and considering the popularity of Apple devices, they will get easier to find. When I compare them to Torx screws I suppose the points rounder shape makes the screwdriver more resistant, which may be an advantage when assembly millions. I am no expert, and I would appreciate if someone has an informed opinion.

Well, let's try the counterargument approach.

Given what we know about fasteners (you need look no further than this thread), why else would Apple choose Pentalobe, of all the options?
