There are nil wooden chop sticks in my toolbox but I do have a couple of Teflon screw drivers and a few alligator leads with a built in 100k or 1M resistors to keep caps discharged, and bamboo skewers are great for holding tiny SMD components in place while you solder them in. Generally though I find wood can have too much moisture content for working in really high voltage or in certain RF environments.
Can't remember when I last got an actual 'boot' from electrickery. Did get one off a megger meter back in my teens when a classmate thought it would be funny to go and zap every unsuspecting class member, and in my 20's I got an RF burn once when working inside a large Antenna tuning unit.
Electric fences.... Should be nil DC, Pulses a few times a second of a few kV @ about 1mA ... lots of bite with little damage...
