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.
Thought they might sell these specialty tools online, but 3 minutes of searching came up with nothing. Might be time to get creative.
Do you have the room to get a Dremel in there the cut it so a regular flathead will work?
If not, maybe try to use needle noise pliers as your screwdriver.
As a last resort, pick up a cheap screwdriver and cut it to make it slotted.
Edit: I love how quickly several people have commented with links to the needed tools. Thanks to all of you!

I have this kit and I remember seeing a similar head in there. Highly recommend it. I’ve used it a bunch.
Nice. Thanks for the link.

Thanks, fixed
Depending on the size, I’ve absolutely gotten small versions of these bits in IT/Electronics repair kits.
