...Actually, this Case is the Case I have decided to replace this time.
The brass-made screwdriver is soft and does not come off, so if you turn the screwdriver with strong force or try to tighten it too hard, it tends to lick the screwdriver. If you try to tighten the screwdriver too hard, it will lick easily. If you lick it, the size of the jet hole will change and you will not be able to use it. It will have to be replaced.
I think it is necessary to use a shorter driver as a countermeasure, and to apply force to the pinpoint and remove it while being conscious of the center of gravity being directly below.

It is really soft and can easily be licked if you put too much force on it, so be careful. Also, there have been cases where a customer has forced the needle gold through to remove a blockage, causing the hole to widen in the opposite direction.
