A triangular square, usually cast aluminium, with a lipped fence along one edge, a 90 and a 45 built into its shape and degree markings along the hypotenuse. It marks square and angled cut lines, guides a circular saw and lays out rafters with the tables printed on it. The one square that lives in the pouch.

Buying tip
The one square you'll carry every day. Use it as a saw guide for square crosscuts.
