Some high-end combination squares have a built-in lip or tab for the purpose of resting the tool hands-free on a piece of wood.
But because most common combination squares lack this handy feature, I developed this inexpensive solution.
Simply attach a 3⁄8“-diameter rare-earth magnet to the head. It allows the square to rest in place, no hands needed. –Charles Mak
