I offer a suggestion that will function for cylinder RPM drop that will not shock you. I've had these plastic pliers conduct and shock me.
i have a huge amount of trouble imagining spark voltage conducting itself through nearly 6" of dry plastic, especially after having to jump through a spark plug boot. and if it did, it should suffer such resistance that it'd be like touching a 9v battery.

i've use them tons of times, maybe over a thousand plug wires by now, never a tickle

maybe they were wet or oily?
