HELP! Tool to turn the lockshield

[Benbens]

Hi everyone, any idea which tools I need to use to turn this lockshield?

 

[CBW]

Looks like a slotted screwdriver is needed.

But my screwdriver is too thin to fit it, is there any very think head screwdriver in the market?

The edge of a 2p coin might be the "tool" you need.

 

[CBW]

Try an 8mm or 10mm slotted head screwdriver - unless that’s what you’re using?

OH heck, a blunt kitchen knife if your desperate...

If you can't work out how to turn it, should you be touching it?
