LCR Trimmer Adjustment Tools

[Teti]

Hi guys, I got back to the electronics hobby after a couple of decades, please advise...
Which one of these Trimmer Resistor Adjustment Tools would you choose? Does it matter? I can't really see any difference physically as long as they are non conductive?
I guess I would choose Vishay for those bragging rights?

Thanks for your answers

Hi
Welcome to the forum.

Does not really matter which one, I have not used mine in god knows how long.

Modern designs do not use pots any more, since everything went digital/microcontroller a lot of adjustments are done in sw and stored din Non volatile memory.

Do not get me wrong, they are still used, just not as often/common.

Usually I use a dollar-store jeweler's screwdriver. Whether conductivity matters depends on what you're working with.

Most trimmer knob/screws are electrically isolated.  It is a good idea to use isolated kind but not really necessary.  They are typically low voltage anyway.  I use any small screw driver I can find within my reach.

Trimmer capacitor is a whole different thing though.

I don't think I have ever paid money for such a tool. For pots I just use a smallscrew driver and the rare occasions when I need something non-metal I just use something I made myself with a little plastic rod or whatever I have at hand. I have sometimes used the inner tube of a ballpoint pen but you can make one with any hard plastic.

Thanks for your answers, I might potentially need it for som RF stuff in the future. I've found some decent ceramic screwdrivers on Amazon, these are non magnetic, so shouldn't interfere with coils. I guess plastic would do the same job but again... those bragging rights ha ha
