Electric testing device and method for hand tools having testing mechanisms

A hand tool system comprising:

• a handle having a first end and a second end;
• a plurality of integral double-ended tool bit members;
• a shank having a proximate end disposed in said first end of said handle and a distal end;
• and
• an electrical circuit test indicator comprising:
• a housing having one or more contacts extending from a bottom end of said housing, said contacts being adapted for engaging corresponding contacts within said handle;
• an electrical circuit means for detecting the presence of electrical energy radiated from an external electrically conductive member;
• one or more lights being coupled to said housing, said lights being lit in a manner indicating a state of the electrical circuit;
• and
• at least one power source coupled to said electrical circuit means, said contacts, and said one or more lights;
• wherein each of said test contacts extends through said bottom surface of said housing such that said contacts said corresponding contacts within said handle;
• wherein said shank comprises means for removably holding said plurality of integral double-ended tool bit members and comprising a unitary one-piece first cylindrical housing having oppositely disposed ends, a second unitary one-piece cylindrical housing having oppositely disposed ends for removably holding first integral double-ended tool bit members, said second housing being slidably received in one said end of the first housing, said first integral double-ended tool bit members being slidably received in said second housing ends, a third unitary one-piece cylindrical housing having oppositely disposed ends for removably holding second integral double-ended tool bit members, said third housing being slidably received in the other end of the first housing, said second integral double-ended tool bit members being slidably received in the third housing ends, wherein one tool bit member is operably disposed in the distal end of the shank.
