Discreet square at an affordable price. He measured truth and square with other squares and standards. There are slight surface changes on the edge of the blade, but not significant. If you were to place it on a perfectly flat surface, you would see small manufacturing flaws, small gaps for light to penetrate. Perhaps a maximum of several thousand variations (just an estimate by eye). This is what you would expect from a tool at an affordable price and shouldn't be a problem for most users.
