I'd stick with Klein, Greenlee, or Ideal... most have lifetime warranties, and are "names" in the electrical field.

Klein and Ideal both offer Basic tool sets...

The Klein one contains:
one side-cutting pliers,
one long-nose pliers,
one diagonal-cutting pliers,
one pump pliers,
one phillips-tip screwdriver,
one wire-bending screwdriver,
three cabinet-tip screwdrivers,
one power-return rule,
one wire stripper/cutter,
one protective eyewear,
one tool belt, and one 8-pocket tool pouch.

The Ideal one is similar, IIRC.

Other small tools:

Should get: 1/2" & 3/4" conduit bender (if you live in a conduit area), and a conduit de-burring screwdriver.

Non-contact voltage detector (you can get them that will also provide voltage readings and continuity detection)

Flashlight

A "10-in-1" type interchangeable tip screwdriver.

A good set of leather "driver" style gloves, and copmfortable kneepads!

BTW, if you really want to spoil him, get the Klein "journeyman" series (cushy handles)!

Tell him good luck for us, and welcome to the field!
