why the handles of testers or screw diver are made of plastic or rubber?

Testers or screw drivers may come in contact with live electrical wiring and if a person comes in contact with the tester, he may get an electric shock.

To prevent this, testers and screw drivers are coated with plastic or rubber because they are insulators, which do not allow electricity to pass through them.
