An edge-trimmer comprises a holdable support arm (2), a cutting head (3) rotatable about a rotation axis thereof (C) and positioned in proximity of an end (2b) of the support arm (2); a motor for moving the cutting head (3) by means of a transmission organ (5), an orientation device (6) of the cutting head (3) in the space connected to the support arm (2) and rotatable about a first rotation axis (A). The orientation device (6) exhibits a rotatable junction (7) which enables the cutting head (3) to further rotate about a second rotation axis (B) which is inclined with respect to the first rotation axis (A).
