This is the perfect size for making sure my table saw blade is 90 and that my rip fence is 90. I also use it on my bandsaw and my jointer. super glued a small rare earth magnet to the side of the the square to have it handy for use on my table saw.

EDIT - after my attempt to improve the accuracy of the square (described in my first review, below), it was still off just a hair - It's actually quite hard to hold the parts absolutely square while the epoxy sets up, so it wasn't a perfect fix. It was only off by about half a millimeter in 3 inches, but I decided to buy another and try for better precision. I gave this one to a friend to help him improve his edge-planing -- like me, he tends to lean to one side or the other, and having this little square is a great accessory to keep us planing at 90°.I bought another of these squares, hoping for better precision, and it WAS better...though still not perfect. However, the second one is so close to dead square that I can trust it to align the blades on my table and miter saws to zero, FAR more accurately than the indicators on the equipment. Like the first one, a few seconds sanding with fine emery paper softened the sharp edges and made it more comfortable to use.Based on the low price, and near-perfect precision, I raised my rating to 4 stars.________________________________________________I like the weight and feel of this little "square". But it wasn't really square - I did the line-flip-line test, and at the end of the 3-inch lines, they were off just shy of 1mm. That may not sound like a huge inaccuracy, but if you were to extend those lines out 12", the disparity would be about 3mm. Not acceptable. I gave it one light whack with a hammer, loosened the rivets just enough to get the two lines to coincide precisely. I'll drip epoxy into the joint, and clamp it at 90 degrees.I had two reasons to buy a small square: (1) I needed a tiny square to do frequent checks for 90 degrees when I'm planing a board's edge (I tend to lean to the right...sort of like my political views), and (2) to check blade setup on my table and miter saws. It was actually good enough as-is for checking board edges, but I want my saw blade setup to be spot on, so I really did need to adjust it to 90 degrees.One other minor issue, there were sharp edges all around, and a couple of small dings on one edge. It took me about 30 seconds with a scrap of used 220 grit sandpaper to soften all the edges.Hey, I read most of the reviews before I bought it, so I knew there was a chance it would be un-square. But at the price, and with a lot more 5-star reviews than 1-star reviews, I thought I'd take a chance on it, and I'm not too disappointed. With just a little work, it will serve my purposes well.

I use this to square everything on my table saw, from the blade to the guides. Perfectly square and well built.May order another one only larger for jigs, band saw and cross cut saw!

Measured it to be +.002" out of square with an indicator. On a comparator, it said 7 minutes proud of 90. Maybe it is good for a tavle saw, but not a machinist. It was also dinged up on arrival.It IS $10. So it makes

It's actually 90â° and the case is nice and sturdy
