ABSTRACT:
A tool for moving first and second mechanical pieces away from each other comprises a first arm with a handgrip portion, a second arm having a proximate end pivotally connected to the first arm, a first notch formed on a free end of the first arm opposite to the handgrip portion, and a second notch formed on the distal free end of the second arm. At least one notch is oriented in a direction defining an acute angle with the longitudinal axis of the corresponding arm, to enable the first and second notches to fully engage generally facing edges of the mechanical pieces before the first and second arms are pivoted manually about the pivotal connection and through the handgrip portion to move the mechanical pieces away from each other.
