Tweezers are small tools used for picking up objects too small to be easily handled with the human hands. They are probably derived from tongs, pincers, or scissors-like pliers used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context they are normally referred to as forceps. Tweezers make use of two third-class levers connected at one fixed end (the fulcrum point of each lever), with the pincers at the others.
