Abstract: A foldable tool kit comprises two abutted elongate first compartments, two abutted second compartments on either side of the first compartment, each second compartment being smaller than the first compartment, and a plurality of hinges each for coupling each of the second compartments to the first compartment or two of the second compartments on the same side. The stored tools are protected from being lost due to the provisions of engaged positioning pegs and holes on the second compartments as well as prevented from mixing due to the provision of covers on the second compartments while carrying.
