Each of these Layout Squares is machined from aircraft aluminum on state-of-the-art CNC equipment. The blade is held square via stainless steel machine screws, ensuring each square will be accurate within two-thousandths of an inch along the entire length of the blade. The 2mm thick blades features engraved 1 mm markings and angle markings on both sides, along with a blue anodized anti-scratch finish.

Features:

1. Each blade has several rows of small drilled holes along its length, ideal for scribing parallel lines to an edge using the included mechanical pencil. These holes are marked and arranged in two rows: the top and bottom rows in 2mm increments.
2. The blades feature miter angles from 5-degrees to 60-degrees in 5-degree increments (plus 22.5 degrees), measured from the corner of the handle to the markings on the blade.
3. A 45-degree cut-out in the handle also enables the quick layout of 45-degree angles.
4. The outer edge of the blade includes a center-finding rule.
5. The anodized aluminum handle has 1/4" and 3/8" offsets, simplifying layout tasks for tenons, dowels, and other joinery on 3/4" stock.
6. The 17 mm thick aluminum handle allows the square to stand upright on its own.
7. Two rare earth magnets in the base help secure it to metal surface, such as a table saw, bandsaw, or jointer.
