The invention comprises of a trimmer body with pivotally mounted handle mechanism attached to a flexible curvature adjuster band going through a plurality of cutting units articulately arranged side by side with a flexible scissor type mechanism attached to every cutting unit and trimmer body to maintain equidistant spacing between cutting units and to prevent the formation of an uneven curvature. The curvature of the cutting section is adjusted with the release of the restraining mechanism with the thumb of one hand and the pivotal movement of the front handle mechanism with the other hand. The one hand operated foliage trimmer's cutting blades are arcually reciprocated by electromagnets. The elongated foliage trimmer's head body and cutting section's hemispherical spatial orientation is adjustable and restrainable with the rear handle mechanism.
