I have one of these:

I think they are called sensor blade in english

I could cut the 0.1mm blade off, and try to use it as a screwdriver, but
that just seems plain stupid

Would grinding a .5 work ?

that\'s a very narrow blade, maybe start with piece of 0.1mm spring
steel wire and rub it on a sharpening stone to form a blade,

  I didn\'t get my point across. You posted what was supposed to be
the smallest screw in the world.

It had a a head the was 0.3mm across. Why would you need a
screwdriver that is 0.1mm wide for that screw.

I think that would be a bad choice, It seems to me a screw driver
0.3mm, or 0.25mm  wide would be better.

Does Klaus have a screw that is smaller than the worlds smallest
screw? OK being a little factitious there.

Klaus, how wide is the slot on the end of the screw you are working on?


I just took some pictures

Watch disassembled:

Screw and 0.2mm sensor blade

www.electronicsdesign.dk/tmp/watch/2.jpg


It\'s a little to wide to fit in the flat slot, so I figured I needed
0.1mm screwdriver

Picture of sensor blade:

www.electronicsdesign.dk/tmp/watch/3.jpg

It\'s a citizen divers watch

 Near as I can figure it, the the distance across the screw head is
0.8mm and I\'ll agree with Liebermann about the slot width being 0.1mm.

https://www.dropbox.com/s/ddxeyrnfy84iniu/watch%20screw.jpg?dl=0

This is huge, at 2.66 times larger than the worlds smallest screw.
To small for my eyes, and I\'m not real shaky, but

at the end of a 2\" screwdriver, I\'m sure it would take a few tries to
hit the slot.

I pulled the smallest screwdriver from my Dollar Store kit and it
measures 1mm and the tip thickness is .3mm. That won\'t work.

This 9pc kit goes down to a 0.5mm blade. $17.69

Yes, that might work. I will go ahead and buy it. Thanks
