Shinwa medium Japanese carpenters square with deeply etched metric full mm graduations inside and outside on both faces.
Made using hard chrome plated stainless steel hardened to Hv320+ for the perfect balance of stability and springiness and no worries about rusty fingermarks.
Japanese carpenters squares are used in the same way as a framing square, with one leg hung over an edge with its face acting as a stock.
Adding a 90/45 degree stopper improves on the versatility of Shinwa's Japanese carpenters square: you can use it for marking parallel to an edge or at 45 degrees, as a caliper, or turn the stopper the other way around and use it as a height gauge.
