This is a useful tool recommended for those who do woodworking or crafts. The edges will catch a little, so you can keep your hand steady and draw a straight line. Skoya is usually L-shaped and does not get caught on the corners, but this T-shaped type is excellent because it can be hooked on the edge of wood etc. so it does not slip easily. Size: approx. 325 x 335mm Material: Stainless steel, made in Japan If there is a problem such as the right angle not coming out, we will replace it. The large type is a large T-shaped skoya made by combining two 30cm rods. Since the ruler itself is thick, it is more suitable for processing cardboard and wood than thin materials. When hooked up in front, the scale on the right side is set off to one side rather than in the middle so that it is easy to see. You can read the 20cm scale on the right side. The ruler is caulked with a pin. * Regarding the accuracy of this product, we combined commercially available stainless steel rulers (with JIS markings) into a triangular shape, set a vertical point 30cm above the horizontal setting line, and assembled the rulers based on this to create a score. At this time, the accuracy target is a rise of 30 cm and a horizontal runout of within ±0.2 mm. When actually finished (there is a crimping process during the process), the error may be slightly larger, so the allowable accuracy is within ±0.5mm. In other words, this means that if you use this Scoya to draw a straight line 30cm long, there is a possibility that the 30cm point at the tip may deviate by up to 0.5mm from the right angle.
