Do they usually have high value resistor inside to limit current to a

yup - you won't even feel a tingle.

PS. Took a small pocket version half way across the globe and to Malta
and back over Christmas, mixed in woth pens and pencils in brief case;
didn't even realise it was there. Only to have it confiscated on a
short day trip between two Middle Eastern countries! Length of the
blade or something.

Was chatting to a friend a while back who had just got back from a
business trip in the middle east. He ended up coming back on a
commercial jet where about 95% of the passengers were returning US
soldiers. A Sargent stood up at the front of the plane, and explained
to them that because (of what he thought were ridiculous) FAA rules,
they now had to pass round a plastic bucket into which they must deposit
any pen knives, screwdrivers or other sharp objects etc. that could
potentially be used as a weapon...

However since they were military personnel, there were allowed to keep
their Ammo, M16s, 9mm side arms, bayonets, and any grenades or claymore
mines they had about their persons!
