This Johnny Square® is proudly Made in the USA and is the first rafter square on the market to use a continuous scribing notch - meaning you can mark and rip lumber to any size you want. This square uses deep cast-in graduations that will never peel off, wear off, fade or smudge and also comes with a low-glare, protective powder-coated finish,it can be used directly with the saw against the square for cross cuts or angled cuts using the etched protractor scale
