Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.
Nice. Thanks for the link.
FYI: There is an “s” missing from the end of that url. https://www.ifixit.com/products/mako-driver-kit-64-precision-bits
