A 12-inch steel rule that slides through a cast head with a 90-degree face, a 45-degree face and a small spirit vial, locked with a knurled nut. It squares, marks 45s, gauges depths and scribes parallel lines. Look for a hardened rule with etched markings and a head that locks without any slop.
Buying tip
Squares, marks 45s, gauges depth and doubles as a small level. The most versatile square you'll own.
