From the historic company that brought us the Combination Square comes the ProSite Combination Protractor (CP505A-12), a 5-in-1 layout device designed for measuring and transferring angles. Starrett's lightweight aluminum tool will help users figure angles for miter and compound cuts, and includes tables for cutting everything from crown molding to rafters. The crown molding conversion feature lets users transfer angles directly onto a miter saw. The two 12-inch-long tensioned legs have a Teflon O-ring for smooth adjustment. Price: $90. 978-249-3551.
