Ours is laser-etched with Lord Kelvin's famous quote, "TO MEASURE IS TO KNOW."
You'll find yourself using this engineering rule all the time and you might wonder how you got along without it! Perfect to use as a straight drawing edge or for quick measuring. It has a super sharp edge and the markings are deeply engraved so they won't wear off.
Fits great in an apron pocket, in a mug on your desk, or slap it onto a magnet on your workbench.
Perfect size for any welder's kit. Can't imagine not having a 6" scale in my kit and I've been at it since 1981
These are better than the $25.00+ machinists rulers.
Very sturdy I use them for scraping flanges and everything else, also a good screw driver
Can't have too many short, straight, well marked rules lying around in the shop.
