Abstract: A cutting tool includes two metal handles each having a first end formed with a mounting portion and a second end formed with a blade portion, and two plastic grips each having an inside formed with a mounting hole mounted on the mounting portion of the respective metal handle. The mounting hole of each of the plastic grips has a first end formed with a first separation slot and a second end formed with a second separation slot. Thus, the plastic grips are detachable from the metal handles when the cutting tool is worn out, so that the plastic grips and the metal handles are separated from each other, thereby facilitating reuse of the plastic grips and the metal handles.
