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 better because it can be hooked on the edge of wood etc. so it does not slip easily. Material: Stainless steel, made in Japan Size: approx. 450 x 480mm If there is a problem such as the right angle not coming out, we will replace it. The extra large type is a large one that combines 45 cm. It is useful for cutting cardboard and DIY carpets and wallpaper. Also recommended for woodworking. 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 25cm scale on the right side when you hang it in front of you. The ruler is caulked with a pin. *About the accuracy of this product: We combine commercially available stainless steel rulers (with JIS markings) into a triangular shape, set a vertical point 45cm above the horizontal setting line, and use this as a reference to assemble the rulers to create a score. At this time, the accuracy target is a rise of 45 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 draw a 45cm straight line using this Scoya, there is a possibility that the 45cm point at the tip may be 0.5mm off from the right angle.
