Yes, it does...but not on the unwashed smelly Pirates! Lol!
I disagree they are handy for picking scraps of food from between your teeth, scratching that bit of your back you can’t quite reach, untying knots in rope, stirring your tea, using as an awl when you inevitably snap it if your using it as an actual screwdriver, throwing at people to express your disgust (the effect is better if you have already snapped the blade and made it very pointy). Pretty versatile tool in my opinion as long as your not actually planning to use it to test for voltage.I would rather carry rat poison in my lunchbox than a neon screwdriver in my toolkit!
Feel the same about simple socket testers, can only tell you it's switched on, or if there's a N/L polarity swap. They cannot detect a N/E polarity swap, or that there is an elevated earth resistance.I disagree they are handy for picking scraps of food from between your teeth, scratching that bit of your back you can’t quite reach, untying knots in rope, stirring your tea, using as an awl when you inevitably snap it if your using it as an actual screwdriver, throwing at people to express your disgust (the effect is better if you have already snapped the blade and made it very pointy).
