Abstract
The present invention relates to a manually-operated ratchet cutter having a moveable and a fixed handle part, the fixed handle part forming a first fixed cutting edge which is developed substantially in the shape of a circular segment and a moveable cutting edge being articulated on an upper end region of the fixed cutting edge for scissor-like cooperation with the fixed cutting edge, the moveable cutting edge moving in a plane parallel to the first cutting edge and cooperating with the latter, and having a ratchet mechanism which comprises a blocking lever and an advance lever and engages in a toothing developed on the outer periphery of the moveable cutting edge. Furthermore, the blocking lever can be moved into a release position. In order to arrive at a development which is simpler in manufacture and more favorable in handling, the invention proposes that the blocking lever (14, 14') engage behind the advance lever (13, 13') in its release position in such a manner that the advance lever (13, 13') is moved out of engagement and at the same time blocks the blocking lever (14, 14') in its release position.
