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.
I have this kit and I remember seeing a similar head in there. Highly recommend it. I’ve used it a bunch.
Same, and I bought one over 6 years ago. Would buy again 11/10
