tweezer

Tweezers are small hand tools used to grasp and manipulate tiny objects. They consist of two slender arms joined at one end and terminating in tips that are brought together by spring action or by squeezing the handles. The alignment of the tips and the force exerted by the spring determine gripping strength and precision.

Tip shapes vary: pointed tips for precision, slanted or curved tips for visibility and access, and blunt tips for broader contact. Materials include stainless steel, plastics, and specialized alloys such as titanium for chemical resistance or electrostatic discharge (ESD) safety. Some tweezers are spring-loaded or locking, and tips can be straight or angled to suit specific tasks.

Common applications include electronics assembly and repair, laboratory handling of micro-parts and specimens, jewelry making and watch repair, and personal grooming for hairs or splinters. Specialized variants exist for medical and scientific use, including ESD-safe, heat-resistant, or corrosion-resistant designs.

Maintenance and safety: to preserve performance, keep tips clean and dry, avoid oil contamination, and periodically check alignment. Sterilize where appropriate, and store tweezers in protective caps or cases. Avoid applying excessive force that could bend or nick the tips, as damage can reduce control and increase the risk of slippage or injury.
