I'm pretty sure I already know the answer, but...

Shouldn't ESD safe ceramic tweezers be non-conductive?

They have to be conductive to get rid of ESD charge I would say...

I thought the idea was to not conduct ESD from your body into your project. Like ceramic trim cap adjusters.

Nope. They need to dissipate the charge. They also work in conjunction with your wrist strap. Without the wrist strap, they are not very effective. As much as they are effective in a first place.

Trim cap adjusters are ceramic to not introduce additional inductance and capacitance, not because of ESD protection.

Now that you say that, it makes sense. I was thinking the point of the ceramic tweezer tips was complete isolation from the circuit (like the screwdrivers).

This is also why you’ll never find simultaneously ESD-safe and VDE insulated screwdrivers and pliers: the former is achieved by making the tools conductive, while the latter is extra-insulated!

i thought the idea is to avoid being electrocuted when working on live circuit unintentionally. luckily i havent buy otherwise i'll get dissapointed before reading this thread. but well 200ohm is better than 0 ohm and possibly damaging some parts of my current metalic tweezer, i need to stay in focus.

VDE insulated tools are for working on live circuits.

Isolating materials accumulate static charges (paper, plastics, fabric, styrofoam) exactly due to this: the charges can't really flow away from the material's body.

However, 0\$\Omega\$ resistance can also be very damaging to devices - the charge flows too fast and creates high current surges that can damage the device. If you short your tweezers to ground and the device has a large charge buildup, you can damage it as the charges flow away from the device too fast. Although the 200\$\Omega\$ alone can help reduce this surge, it may be insufficient if the charge amounts hundreds or thousands of volts. That is why Ataradov mentioned the tweezers require the ESD strap as well, which has a typical resistance of 1M\$\Omega\$ so it can severely limit the surge of charges flowing away from the device.

The ESD strap and equipment cannot be used in high voltage installations.

Any ESD for electronics protection related tools/equiments are NOT designed/made for protecting human life.
