Abstract
Abstract A tool that is particularly suitable for the installation of objects that require tensioning and severing. A tensioning member is operated through a toggle linkage that collapses when a pre-determined level of tensioning is reached and actuates a cutoff lever. The result is severance of the tensioned object with reduced shock loading. In addition the tool is easy to operate; the tensioning level is accurately and reliably adjustable; and the severed object is controllably ejected from the tool.
