This cabinetmaker's square is used to lay out or transfer measurements quickly and accurately - you always have an ample reference face against your workpiece without having to flip the square. This also simplifies working in two axes at once (eg, measuring in 50mm and over 38mm), substantially reducing the chance of error when measuring and marking two dimensions.

The stainless steel blade is 77mm wide and 152mm long and is machine ground on all four edges. The rule is graduated to 100mm along both edges and across one end to 70mm. The diamond cutout in the blade holds a pencil tip in position and makes it easy to draw lines parallel to an edge. The locking mechanism has a notched pin like those on combination squares, with the blade bearing on polished, hardened steel reference pins set in the body. Accurate and well made. Weight: 317g.
