Tweezers

Tweezers are small hand-operated tools with two joined arms that grip objects when their free ends are pressed together.

Connect

Cantilever: A beam or structure supported at one end and free at the other. Each arm bends like a cantilever when the handles are pressed.
Spring steel: Steel formulated to withstand repeated elastic deformation and return to its original shape. It supplies durable spring action in many metal tweezers.
Eyebrow grooming: The removal and shaping of eyebrow hairs using grooming tools. Slant-tip tweezers are commonly used to grasp individual hairs.
Pliers: A hand tool with pivoted jaws for gripping, bending, or cutting objects. Pliers use a hinge and handles to amplify force rather than flexible joined arms.
Elasticity: The ability of a material to deform under force and return to its original shape when the force is removed. Elastic recovery opens the arms again after the grip is released.
Stainless steel: An iron-based alloy containing enough chromium to resist corrosion. Its corrosion resistance suits tweezers exposed to moisture or cleaning.
Electronics assembly: The process of fitting and connecting components to build electronic devices. Fine, often anti-static tweezers handle small components without fingers.
Tongs: A tool with two arms joined at one end, used to grasp and lift objects. Tongs usually grip larger objects with separated arms and broader ends.
Beam theory: The engineering analysis of how beams respond to loads through bending, shear, and deflection. It predicts how arm length and thickness affect tip force and bending.
Ceramic: A hard, inorganic, nonmetallic material shaped and hardened by heat. Ceramic tweezers can resist heat and avoid electrical conduction.
