A hand tool (40) is disclosed for terminating an optical fiber (26) of a cable (10) to a crimp contact (14) of a connector. The tool includes a carriage assembly (60) that utilizes a delicate spring (250) to provide a desired abutting force at the point of engagement of the optical fiber with the connector contact. The carriage (64) slides along a pair of guide rails (70, 72) rigidly held by a base (62). A counterweight (80) is also arranged to slide on the guide rails and is coupled to the carriage by means of two pulleys (106) and a thin steel cable (230) so that when the carriage moves in one direction the counterweight moves in an opposite direction an equal amount. The counter weight has a mass that is substantially equal to the combined masses of the carriage and the cable so that the system is balanced and unaffected by gravity or sudden movements, thereby assuring that the abutting force is maintained within desirable limits, even when the tool is tilted somewhat with respect to the horizontal plane.
