Such devices can work normally from 20 V. But if you work with them for too long, the pencil may catch fire. During engraving, the temperature of the stylus reaches 300 degrees.

Rubber in contact with the cutting edge of the knife? I happened once, many years ago, to get under a non-releasing phase, in one hand a phase, in the other zero. Thanks to my friends, they saved me. Until now, as I recall, so nervous trembling.

The right hand is in a glove, and the left hand is without it, and the author touches her handle with metal rivets. And the gloves are not real dielectric, but some kind of household gloves. Generally joke with a mains voltage of 230 V extremely dangerous! For things like this you have to use voltage no higher than 50 V, galvanically isolated from the network.
