Type: Size: 1m Size: 1m Aluminum Base Square Shinwa Measurement (Shinwa 1000mm 74120 I am selling this because I accidentally purchased it from the shop. Regarding the dent in photo 6, it was there from the beginning, so I think it's something necessary from the process of making the ruler. I have never used it, but I took it out of the bag once, so I will describe it as "like new". This square is suitable for woodworking. It is also useful for assembling wooden molds from a surface plate or measuring right angles.
