A trimmer having a first cutting blade having a first cutting edge and a second cutting blade having a second cutting edge. A first drive gear assembly cooperates with the first and second cutting blades so that as the first drive gear assembly rotates around the first axis, the first and second cutting blades are caused to reciprocatingly move, one relative to the other, respectively in first and second paths to produce a cutting action. A second drive gear assembly has a second drive gear that has teeth that are in mesh with teeth on the first drive gear assembly. The second drive gear is rotatable around a second axis to thereby cause the first drive gear assembly to be rotated in the first rotational direction. A powered drive assembly rotates the second drive gear around a second axis in the one rotational direction. The teeth on the first drive gear assembly are defined by a first bevel gear. The second gear is a bevel gear that is in mesh with the first bevel gear.
