Great demo.

i noticed you were using a scredriver with a much smaller blad as the slit in the screws from the crownwheel. Are you not afraid for damaging the slit in the screw?

also your tweezers are looking very rough. I always make an effort to polish the outside of the tweezer to minimize the  change of scratching the delicate parts. Am I overly worried here?

thanks

In my experience, perfectly matching blade width to a screw cut is not so important as having a vertical and precise motion, and Mark certainly has one. And the outside of tweezers, rough or smooth, doesn't scratch any part.
