Abstract

Abstract A tool case, which includes a plurality of pairs of casings respectively connected in series by means of connecting strip portions therebetween, permitting two casings to relatively turn outward with the adjacent two casings capable of being relatively turned inward so that the intermediate casings can be completely received in a space which is defined by the first and the last casings when the first and the last casings are relatively turned inward to close up together. The casings comprises a variety of recess holes for receiving a variety of hand tools. The first and the last casings have hand-hold portions which can be incorporated together for the holding of the hand when the casings are relatively closed up together.
