A bipolar high-frequency incision tool for an endoscope having a flexible insertion portion configured to be inserted into a body cavity. First and second elongated electrodes mounted to a distal end of the insertion portion so as to be movable between an open position and a closed position. The first and second electrodes being connected with conductive wires that provide a high frequency voltage, and having corresponding first and second surfaces. The first and second surfaces are spaced apart from each other when the first and second electrodes are in an open position, and the first and second electrodes remain spaced from one another when the first and second electrodes are moved to the closed position. In addition, the first and second surfaces each have inwardly tapered side surfaces configured to form respective blade edges.
