Abstract
A tool is disclosed for lifting and carrying a bundle of shakes or shingles by hooking onto the band of material that holds the bundle together. The tool includes a handle and at least two hooks attached to the handle for engaging the band of the bundle. The handle is designed to prevent the skinning of a roofer's knuckles or the pinching of his fingers by providing adequate separation between a grip portion of the handle and a portion of the handle that supports the hooks. The hooks include offsets which help align the tool with the center of gravity of the bundle and may be provided with gaffs to ease their insertion under the band. In certain embodiments of this invention the handle is modified to provide a sharp cutting edge for puncturing, chopping or slicing through the band.
