Abstract
A tool for performing lopping, pruning and similar operations includes a housing assembly formed of a pair of telescoping tubular sections. The tool also includes a tool head, a head line and an actuating line. The tool head, which is connected to one end of a tubular section, preferably includes a spring-biased blade coupled to the head line which is connected to a slidable block. The actuating line, while engaging the slidable block so that tensioning the actuating line causes movement of the blade, is also slidable relative to the block upon relative movement of the tubular sections.
