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.
in a case i only needed it once, i would solder or power glue something to it to use as a wings handle.
… but that’s just me. I’m like eccentric MacGuyver.
