If you are working with Metripack connectors you are eventually going to need to remove a terminal from the connector.  This tool makes it easy!  Simply insert the end of the tool into the small opening next to the terminal in the face of the connector.  The terminal can then be pulled backward and out of the connector.  (Note!  For pull-to-seat terminals this tool must be inserted in the back of the connector, just over the wire, and the terminal pushed forward to remove.)
