Aluminum Carpenter's Speed Square
The speed square is the square to own if you're only going to own one square. It's the carpenter's multi-use friend for use as a protractor, rafter-, tri-, miter- or framing square, as well as a circular-saw guide. Measures 7" on the short sides, with degree markings and an inch ruler along one edge, and both top-cut and common scales, and a nail gauge. Made of cast aluminum.
