I used to use 3' long wooden stick with 10" long wire tip on it to attract 
4' long TC arcs and never had a single accident or funny feeling in my body 
in doing so.Wood must be dry and without varnish or coating of any kind 
over its surface and arcs to be let just to the protruding wire (not to the 
stick surface alone  becouse it could be easily set on fire)
