Abstract
A toolbox that has an outer housing, an inner housing and a number of storage trays. The outer housing is removable from the inner housing. To use the toolbox, the outer housing is removed and placed on top of the inner housing. Then, alternate drawers are removed from the inner housing and placed in the upper housing. This creates a number of drawers that have spaces between them. The spaces are large enough to see into the drawers and to reach in and obtain tools. Once the tools have been positioned, they are readily accessible for use. When the job is done, the drawers are returned to the inner housing, the outer housing is removed and fitted over the inner housing for storage. Once locked into place, the complete toolbox can then be transported as desired.
