Hedge trimmer is a powered garden tool with reciprocating, twin-action blades used for the regular maintenance and shaping of hedges, bushes, and shrubs, achieving precision and maintaining a manicured appearance. It differs from a hedge cutter, which handles thicker, more substantial branches, while a trimmer is ideal for smaller growth. Hedge trimmers are available in electric, battery-powered, and gas-powered models, with features like dual-sided or single-sided blades, various lengths, and comfort-oriented designs such as ergonomic grips and vibration reduction.
