MATSUI Precision Try Squares Precision try squares from MATSUI are highly accurate instruments made of rustproof stainless steel. In addition to the inside and outside scales, the thin blade features a Ura-me edge. This scale lets you determine the largest possible square cross-section that can be obtained from a round piece of timber. Simply place the square’s Ura-me scale across the face of the round timber to read off the value. One graduation mark along the Ura-me edge equals 1.414 mm (square root of 2).

Veritas Precision Square Metric Version This could easily become the most-used measuring tool in your shop. An ideal size for cabinetmaking, it has the accuracy of an engineer's square (0.001" per inch of length = 0.15 mm over the 150 mm leg). All four edges are ground, and both faces are graduated on the inside and outside edges, the 80 mm leg in 1/2 mm and the 150 mm leg in 1 mm. Click picture to see the scales in better quality.

It is useful not only for general layout and checking whether surfaces are flat or straight, but also for machine set-up, since it lets you measure and check for square on the same plane. Since the 20 mm wide legs are made from chrome-plated high-carbon steel, they can be marked upon with pencil for direct-reference use.

The relieved interior corner ensures that the square seats well, even over saw whiskers. The markings are etched and black-filled for ease of reading. Its thin, compact size fits easily into an apron slot or pocket so it's there when you need it.
Made in USA.
