The IRWIN 12-inch Combination Square (model 1794469) is pretty popular among both DIY folks and pros. It's known for being sturdy and affordable. Our research shows it has measurement scales on all sides of the ruler—three sides with imperial (⅛, 1/16, and 1/32 inches) and one side with metric in millimeters. This dual system can be handy if you switch between metric and imperial measurements.
That said, the metric measurements might not always be the best fit if you're after metric precision. Some folks mentioned that the metric scale's position can be a bit tricky for precision tasks like scribing or measuring depth, which could be a concern if you rely on metric measurements a lot.
Apart from that, people really like its durability and the clear, etched markings. It's made with strong materials, which makes it reliable—a big plus for woodworking tools where you need accurate measurements.
So, overall, the IRWIN Combination Square is a good option, especially if you need something versatile for both measurement systems.
But if your projects require precise metric-only tools, you might want to think about whether this meets your needs or look at some other options more focused on metric specs.
It's a solid, budget-friendly choice for woodworking as long as its metric layout works for you.
