The present invention relates to a hand-held type opening and closing action tool in the form having front active pieces for cutting and other operations adapted to perform opening and closing motion around the axis of a pivot, as found in manual sharp-edged tools and manual tools, such as scissors, pliers, nippers, and strippers. The tool comprises a hand-holdable cover case formed with an elongated guide hole, opening and closing operation levers pivotally mounted on the case and normally resiliently urged in the direction to spread out from the case, and front active pieces operatively connected to the levers to bear the resilient force on the levers and adapted to be opened and closed by the levers, the arrangement being such that the levers are prostrated into the sunken state in the case against the resilient force and in this state the pivot of the pieces is slid along the elongated guide hole of the case, whereby the pieces are also received in the case in the sunken state.
