A portable handheld edge cutter ( 1 ) has a cutterhead ( 2 ) fixed to a guide tube ( 4 ). Two wheels ( 6, 7 ) are attached to the cutterhead ( 2 ). The cutterhead ( 2 ) includes a gear unit mounted in a gear housing ( 8 ). A first wheel ( 7 ) is rotatably journalled on a first end ( 27 ) of the gear housing ( 8 ). On the opposite-lying end ( 28 ) of the gear housing ( 8 ), a cutting knife ( 9 ) is mounted and is rotatably driven by the output shaft ( 18 ) of the gear unit. In order to achieve a simple assembly of the edge cutter ( 1 ) and to protect the gear housing ( 8 ) against wear, the second wheel ( 6 ) is mounted between the gear housing ( 8 ) and the cutting knife ( 9 ) and that the two wheels ( 6, 7 ) are journalled coaxially to the output shaft ( 18 ).
