FAQ:

Q: What is the best combination square to buy?

A: A combo square is a great all-purpose marking tool—and the Irwin has a better build quality than other, more expensive rivals we tested. *At the time of publishing, the price was $14. Of the six combination squares that we tested, the best for most people is the Irwin 1794469 12-inch Combination Square (about $11).

Q: What is the best square tool to buy?

A: The Irwin is a very nice tool for the price. Some combination squares, like the much vaunted Starrett (about $115), can cost quite a lot, but the differences between the low end and the high end will likely be lost on the occasional user or DIYer. Starretts have durable cast iron bodies and microscopically precise measurement markings.
