Conceived by carpenters and designed by MIT engineers, the M1 Caliber tool eliminates the need to measure and mark materials before cutting them. It clamps to almost any kind of saw fence and outputs measurements of materials slid underneath its wheel on a backlit LCD screen, making your cutting work more accurate, faster, and safer than traditional methods. The integrated clamp allows the M1 to attach to most saws and flat surfaces, dramatically increasing your saw’s capability, with one click of the clamp. Made in the USA. A funded Kickstarter.
