First, I get it. This square is really expensive. But before I purchased this, I had no idea how my woodworking was being compromised by having tools that were set up using a square that I *thought* was 90 degrees, or close enough (so I thought). From tablesaw set up, to miter gauge set up, to jointer set up, to dovetail jig set up, to checking cases for square - everything. The errors introduced by my cheaper, inaccurate squares made *everything* more difficult. And the errors compound themselves as work proceeds. Knowing that I now have a square that is consistently, and truly accurate has changed my work considerably. I've had to re-tune all my woodworking tools. I saw videos on-line regarding combinate square shootouts and how to tune-up an insufficiently calibrated square, but I didn't want to go down that path. If all you do is rough carpentry or nothing requires precision, you don't need this square. But if you're a woodworker, bite the bullet, close your eyes, take a deep breath, and spend the money on this square.

I was using an empire combination square that just would not stay square (about 1/16" off at 12"). I finally bit the bullet and spent the money on the Starrett after seeing nothing but positive raves about their quality and accuracy. I am not disappointed! This square is perfectly square out of the box and feels very sturdy in my hands. The marks go all the way down to 64ths, but my old eyes are having a hard time seeing that small so I stick with 32nds. Great product. If you are on the fence about it, do it, it's worth the expense if you need accuracy.

Inzwischen mein zweiter Starret, die Qualität ist einfach gut. Da ich mit einem Kombinationswinkel nie messe, sondern immer nur anreiße, ist mir die 4R-Skalierung in inch egal, solange dieser nur die Hälfte vom metrischen 11MH-300 kostet.

This combination square is great. I am all about saving money on tools any time I can. Gauges and measuring equipment though are one of those areas where the money spent is worth it for a lifetime. This square is right on point and I can count on it for precision 45 degree and 90 degree checks and marks. I am glad I went with the starret model. It costs more but is worth it in the long run. The faces were machined perfectly flat on the square I received and all of the degree measurements check out on several accurate protractors. It feels solid while being used and the ruler doe not move at all when the nut is tightened. I could not ask for more from a combo square.Dimensions can be seen in the photos I have attached. One side has 1/32" graduations.Included in the box will be a certification from the factory.Pros:*Very precise*Well built*SturdyCons:*NoneAdditional Considerations:When it comes to gauges. Spend the money. Its worth it in the long run.Overall: 5/5 stars (>=.5 rounds up, 5 starsIf you have any further questions regarding the product in my review please leave a comment below and I will get back to you as soon as possible.

It's a Starrett... when it comes to precision marking and measuring tools NO ONE does it better. My 6 inch combination square is from another manufacturer. I bought it at a big box home center. It is accurate and it works OK but it doesn't compare to this 12 inch Starrett. The Starrett is heavier which gives it a great feel when you are working with it. The Starrett has great adjusting components too. A slight twist of the knob with my thumb and the rule is locked in place. No wiggles. No wobbles. To get that performance from the home center brand I have to really crank down with my thumb and index finger. The method used for marking the graduations also make this a superior tool. Starrett uses laser engraving. Not so with a less expensive brand. That means your graduations will (eventually) wear off. My cheapy 6 inch is already showing signs of wear after two years. The Starrett looks the same as when I took it out of the box-and I use it A LOT more. Over your lifetime you can by one Starrett or several of the home center brand. Oh... did I mention it's made in the USA?
