In 1878, Laroy S. Starrett designed and patented the combination square. His invention was a multipurpose
layout and measuring tool for machinists and it was rapidly adopted in the trade.

Woodworking books of the period don’t mention this tool. After all, the try square and marking gauge were common and effective, so it took a while for the transition from machine shop to cabinetshop. Today, most woodworkers own a combination square, but few know all of its uses, and many try to get by with inferior versions.
