trimmer

A trimmer is a term used for several tools and components that perform trimming or adjustment operations. It can refer to grooming devices, garden tools, and electronic adjustment components, among other uses.

In personal grooming, a trimmer is a compact electric device designed to trim facial and body hair. It typically features close-cutting blades, an adjustable guard or comb to control length, and runs on rechargeable batteries or wall power. Many models are designed to be water-resistant or waterproof for use in the shower. Maintenance usually involves cleaning hair from the blades and applying light oil to moving parts to keep performance smooth.

In gardening, a hedge or shrub trimmer is a longer tool with reciprocating blades used to shape and prune hedges and bushes. These come in electric corded, cordless battery-powered, and gasoline-powered varieties. They provide different blade lengths and tooth configurations to handle light shaping or heavy pruning. Safety features often include blade guards, hand guards, dual triggers, and ergonomic handles to reduce user fatigue and risk of injury.

In electronics, a trimmer refers to a small adjustable component used to calibrate circuits. A trimmer potentiometer provides a variable resistance, while a trimmer capacitor adjusts capacitance. These components are typically adjusted with a small screwdriver and are mounted on printed circuit boards or inside equipment. They are usually sealed to protect against dust and moisture and are used during manufacturing or servicing to fine-tune performance.

The term derives from the act of trimming or cutting back to achieve a desired result, and its meaning depends on the context of grooming, gardening, or electronics.
