O'Connor Tweezer Dexterity Test 

This test measures the speed with which an employee using tweezers or some similar instrument is able to pick up pins or similar small items one at a time and place them in small holes on a board or other metal plate. It very much resembles the Finger Dexterity Test but since a finger eye-hand coordination is required in the Tweezer Dexterity Test, some employees can make good scores in the Finger Dexterity Test, but not in this test. A high score indicates manual aptitude for work involving precision and steadiness in the use of small hand tools, such as the forceps in the hands of the anatomist, or surgeon, or biological laboratory worker, or the tweezers in the hands of a watch repairer or stamp collector.
