I can't recommend you wrap Tools with electrical tape and use them as "insulated", I agree with this, it is dangerous especially for someone not used to working with electrical on a daily basis. I wrap some of my drivers but complacency has lead to blowing up the side of boxes etc. Especially the pliers, it is impossible to wrap them as tight as the manufacturer coats them. As an electrician I do carry Non-insulated tools but thats because working live isn't as common as dead. They are expensive but well worth the investment.
