Editor's Review: Combination Squares

by Steve Latta

review date: December 1, 2002

A combination square is a vital tool for performing the most basic shop operations, such as layout, marking, measuring, and machinery setup. Its versatility is unparalleled by any other single tool. The two main components of a combination square are the head and the blade?what manufacturers call a two-piece set?and that's all you get with most of the lower-priced tools. In the higher price brackets, the major brands offer center heads and protractor heads, resulting in a four-piece set, for about double the cost of the two-piece set. Fortunately, buying a combination square is likely to be a one-time purchase because all of the better models will outlast you.

The Johnson Level and Tool model I tested was out of square and had an arched blade. The stamped chrome blade was difficult to read.

It was out of square at the store. Since it was on clearance I picked one up. Later, I filed down the little nibs on the base to get it square. As soon as I slid the ruler down midway, checked it again, it was out of square. It seems like the aluminum will flex to a certain extent and get worn down after a few adjustments. Save up for a Starrett!
