2 pin nuts on SSL preamp - what's the tool called?

[NoisyIndividual]

The BSS and Drawmer just use regular hex pot nuts.

It’s a collet knob that uses a collet tool as others have already said.

That looks cool. I can't quite see from the image...does it have a hole for the pot shaft?

Yes, I have the same one.

The only issue is due to it being double sided, if you really need to apply pressure it digs into your palm.

Thanks everyone . To clarify, some people are suggesting tools to get the knobs off, what I was looking for was a tool to get the nut off a pot that was recessed about 5mm into the face plate. It needs to be hollow to allow for the pot shaft and not too thick because there's only a couple of mm clearance in the recess. I've improvised with the needle nose pliers for this job but have a destuffing tool on the way for next time.
