I have used the same product (aluminum version) for a long time, and it is a ruler that is indispensable for drawing to a bar. The dimension line got faint, so I replaced it.
I would like if there is a similar product of even larger size.
It is convenient because it can bring out 45 degrees and 90 degrees soon. I think that this is enough if it is DIY. Polka stopping ruler is sold cheaper from Inoue tool, so it may be better there. (Probably because the quality is equivalent) If you sold an aluminum type it was ★ 4 with the price difference between Inoue tooling and buying it.
