TOH Tested: Combination Squares

Price: About $36; lagesseproducts.com

At 2 inches wide, the aluminum head of this square won't tip when you're marking pipes and tubing. It's also great for trueing a table-saw blade or checking an inside corner for square. That said, this isn't the choice for marking 1× or other thin stock, since you'd have to prop up the material to meet the blade.
