Great small combo square
I recently purchased the Johnson Level & Tool 406EM Professional Inch/Metric Combination Square, and I must say, it has far exceeded my expectations in terms of quality, value, and usability. I have a number of larger squares but needed something smaller for a project. Given its surprisingly affordable price, I was initially skeptical about its performance and durability. However, after using it extensively in various projects, I'm thoroughly impressed. It's a tool that not only meets but exceeds expectations, and I wholeheartedly recommend it to anyone in the market for a reliable combination square.

Good med. Size square. Good Quality! Strong, and comes with a scribe screwed in on the bottom. I been using it daily for work for over 5 yrs and it's still in great condition. As a press break operator making parts for aerospace I definitely recommend this square!

What you see isn't what you get.
What's advertised in the photos isn't what you get. The photos show black lettering which is very easy to read under most lighting conditions but what I received was a blade that had all of the numbers and gradations stamped. If you scroll down into the description it does mention that all of the lettering is stamped but it only seems fair that if they are going to post photos of the product then it should match with what they are going to send you. Other than that the accuracy and squareness appear to be good. Returning this item.
