Rated 4.5 out of 5 by 10 reviewers.
Rated 5 out of 5 by Exactly what I needed The Empire 12" combination square is a great product: the deep rule marks on the blade are easy to read and will withstand a lot of wear and tear, the leveling vial is easy to read, the drawbolt holds the blade firmly in place, the blade slides easily through the blade guide, and the handle allows for easy 45° and 90° angle markings. The blade is double-marked on both sides in inches (broken into 1/8", 1/16", and 1/32" subdivisions, no metrics) so it's easy to use the square whether you're right-handed or left-handed. The packaging shows three levels of product on it: "Good, Better, Pro," and the square I got is marked as "Better;" therefore, I'm not sure why the product description on here shows it as "professional." On the other hand, the liquid in the leveling tube is yellow, not blue, which lines up with the professional description (versus the blue liquid used in the "normal" square. Not that it necessarily affects the effectiveness of the square, but I really appreciate that this product is made in my home state of Wisconsin. Very cool. TL;DR: This is a great square, especially for the price! July 31, 2014
Rated 4 out of 5 by Good basic square First of all, I don't know why this is described as a "Professional" tool when the packaging indicates otherwise ("Better" out of "Good-Better-Pro"). I suppose anything can be professional if the user is paid for the work, so it's just semantics. I like this tool. It has the usual features of a small low-priced combination square. The blade is strong, but not unbend-able, so be somewhat careful with it. The aluminum head is fairly wide at 3/4". The best part, for me, is the reversible draw-bolt/lock, which is also fixed in alignment so you do not have to re-align it while reassembling the square. The lock is reversible so that you can select which graduation and scale you want to view on the preferred side of use. I am right-handed and like the scale to be on my side and be the view with 1/16" graduations. This can easily be arranged. The blade material is base steel, not stainless, so you must oil it frequently to keep the rust to a minimum. The oil will help keep it easy to slide anyway, so that's not big deal, but it will come off on your hands and that can complicate fine wood work. The small spring in the lock is base steel also, so it will probably be the first part to go bad, not that it would prevent you from using the square. November 27, 2013
Rated 4 out of 5 by Decent Square This is a decent combination square. Both the handle and the rule seem to be made from aluminum, instead of steel which is what I'm used to seeing these made from. That makes it a little lighter, but it also feels a little less rugged than the steel versions. That said, the construction quality is good, the mechanism works well, so I'd say it does its job.

Rated 5 out of 5 by Works great, durable This square is basic but durable and easy to use. It is made of aluminum and light. The ruler's marks are stamped deep, not painted which are a plus. I have used this with ease in furniture construction and would recommend it to anyone in need of one. July 26, 2014
Rated 5 out of 5 by Well made, smooth operation This is a sturdy, well-made square and the mechanism slides smoothly. The markings on the rule are deeply embedded so they should last a long time regardless of how often the slider is moved. A good value. October 24, 2013
