You probably won't find that screwdriver at local hardware store though. I had endless issues finding even semi-common torx bits at Lowe's.
I've used mine to take apart every conceivable consumer electronic, and through social bits for Nintendo, Apple, etc are priceless.
I also got the magnetic mat, a Christmas gift from my wife, and when disassembling things with lots of screws is useful for drawing out the device for their location.
