INCRA’s precision Guaranteed Square is the most accurate that you will find anywhere. Each square is guaranteed +/- 0.001" from nominal along either side of the blade. Unlike conventional tools that use separate blades and handles, this innovative design uses the most advanced manufacturing methods available to carve a solid 1/4"-thick slab of hardened aluminum into a one-piece, gold-anodized spine that serves as both the central part of the handle and the blade for exceptional accuracy and consistency.
The spine also projects beyond the handle’s cheek plates on the inside of the square, producing a support lip that makes it easier for the user to keep the handle flat on the edge of a board. There’s even a recess machined into the spine’s inside corner to keep the fuzzy corner of a board from affecting the measurement.
