Tweezers are precision handheld tools designed to grasp, hold, or manipulate small objects inaccessible to human fingers. Modern tweezers integrate advanced materials and ergonomic designs to meet demands in electronics, healthcare, laboratory research, and industrial manufacturing. Their importance lies in enabling precise handling of components at micro and nano scales, critical for semiconductor assembly, surgical procedures, and material science applications.
