We had one of those as standard equipment, called it the Cattle Prod. Used it for 'cleaning' rebuilt CRTs before installing them.

Rebuilts tended to arc due to contaminant particles. The Cattle Prod made the particles incandesce and fly around until they stuck somewhere, thus minimizing arcing after installation.
