Abstract
A hedge trimmer has at least one moveable blade and a second blade. The second blade has trapezoidal teeth. The first blade has rectangular teeth which have a broadened end portion, but, contrary to the prior art, the teeth of the first blade are at least twice as long as those of the second blade. As in the prior art hedge trimmers, the broadest part of each tooth is defined by two juncture points, one on each side of the tooth. For additional safety, in accordance with the invention, the maximum distance between adjacent juncture points of adjacent teeth is 14 mm.
