The multifunctional Japanese square is used to measure three-dimensional elements. The corner angle has a simple measuring scale. It has a scale for measuring angles from 0 to 90º and a limiter for 45º and 90º angles. The rectangular shape allows for precise measurements at the corners, which can facilitate the transfer of diagonal angles to two adjacent sides of the workpiece. A corner rule can help you define parallel lines. Thanks to it, we can quickly determine the diameter of the drill. The 3D square is a universal device, indispensable in every DIY workshop. https://elecena.pl/product/22623931/japanese-carpentry-square-3d-corner-multifunction-angle-ruler 2023-02-23 https://elecena.pl/product/22623931/japanese-carpentry-square-3d-corner-multifunction-angle-ruler 2025-10-28
