Abstract
The inventive tool has two elongated tongs pivoted together at corresponding ends, to have the remote tong ends gapped apart when opened and touching when closed. A spring biases the tongs to opened positions, and stops center the tongs when fully opened. A flexible tong line is connected at its ends to intermediate locations of the respective tongs and is routed as three separated spans crossing between the tongs; two tong line spans crossing from the end connections and the third or intermediate tong line span crossing closer to the pivoted ends. A flexible pull line is secured to the intermediate tong line span. With the tool carried on an extension pole, an operator can position the tong ends and tension the pull line to grip remote objects, such as gripping and removing Leaves from an overhead gutter.
