The classic, you can't go wrong
This square has been around longer than my Grandfather, and I'm a grandfather. Cheap and accurate. I use it for most constructions and some woodworking.

great value for an inexpensive square that's square
This is a duplicate of my review of the 7" Swanson speed square. They're both made of the same aluminum alloy, both equally sturdy, both use the same embossed lettering, etc. The only difference is the size and the fact that the 12" comes with a removable layout bar for faster setups. I recommend them both. This is a very good value for a low-end speed square. It's square! great for aligning power saw blades with tops and fences. This is not a precision cut tool, but it does what it's intended to do. I also have the 12" Swanson SO107 12-inch Speed Square, which is also inexpensive and useful. I have actually found the 12" to be more useful in my wordworking, especially with blade alignment, etc. Both come with a booklet that describes use for framing, stairs, rafters, etc. They are both made of thick 3/16" aluminum alloy and are very sturdy. The 7" is easier to carry around, but I use the 12" more for basic woodworking. Recommended

Bought the 12 inch tool. It is great quality while not being too heavy.

Decent
Overall, this is a solid, heavy square. Not sure if I will ever use the extra pieces, as I am more of a DIY guy. As seen in the photo, quality control on printing isn't the best but it likely won't affect it's use.

Multipurpose tool, reasonable price
Very handy tool. I use it for basic measurements on lumber, and as a guide for cuts with my cordless circular saw. I guess I should build some stairs to make use of more of the features.... someday....

Swanson-One of the tool names that mean quality and value.
I have Swanson squares in the 7 inch metal and plastic versions. They are incredibly accurate, each and every one. Do the "flip" test and you will see what I mean. I bought these to use to square up my table saw fence to the table. Worked great. You will find a ton of uses for these things to make sure everything from drawers to shelving units are perfectly square.
