A first pocket is attached to the upper front corner of the first side of the support. A second pocket is attached to the first side of the support adjacent to the first pocket. A third pocket for elongated substantially cylindrical objects such as drill bits, allen wrenches, hole punches, nail sets, files, and screwdrivers is attached to the first side of the support below the first pocket. A fourth pocket for holding an oblong tool such as a razor knife, wire stripper, fuse puller, ratchet, or pocket knife is attached to the front side of the second pocket. A fifth pocket for holding a writing instrument is attached to the front side of the third pocket. The tool holder is secured to the waist of the user by inserting a belt in a tunnel of material at the top of the support.
