Limpets certainly can be on the tricky (not to mention Sticky!) side, but when they are underwater
you can usually manage to surprise them and slip a sharp knife underneath, while they are not
looking, but you have to be fast!!  I like the Alchohol idea - puts people to sleep, so should work
on molluscs as well!  All you need here is a friend who is diabetic and can give you a needle every
now and then, and some rubbing alchohol.
