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.
Your gonna need a teeny tiny grinder. Maybe a dremmel?
Everyone should have a Dremel. Damn thing is so useful.
They really are and they’re not prohibitively expensive either. Use mine all the time.
Everyone should have a bit-set that includes standard spanner bits. Especially in this community.
At that point you might as well just do it to the screw instead and use the normal screwdriver.
