Bought 2 of these squares for my woodshop -- 1 for general woodworking and the other for machine setup and depth gauging. Unlike most squares, the graduations are deeply-imbedded and are highlighted in black, making it easy to read. I've been using both regulary for over a year and the markings show no wear. I maintain the squares often, by sliding the end of a used candle across the blade surfaces. Then a quick wipe with a rag. This not only lubricates the slide action of the blade, but minimizes blade wear, prevents rusting and retains the highlighted markings. When hang the squares for easy access, I make sure the hanger does not come in contact with the bubble to avoid breakage. This square is well worth the money and truly deserves to be treated as a precision woodworking tool!
