Shinwa H101-C 300 mm Rigid "Zero Glare" Metric Machinist Ruler/Rule Scale .5 mm & mm Markings

Very nice quality. Rigid, not flexible like some cheap rulers. Good price for a quality ruler. I needed a Metric ruler since pretty much all 3D printing use the Metric system. I've been converting to imperial for years and finally broke down. 😃

I measured things as part of my jobs for my whole life (too many years to say). Mostly used ft. inches. and down to less than one ten thousandth of an inch. I never had any affection for the metric system but have recently been laying out hole patters in MM's to be drilled on a drill press. I got so sick of multiplying by .03937 that I broke down and bought my first metric scale. Now I just use the metric number its much easier. In precision work the conversions will continue as machinery is still in imperial measurements but I am so glad to have bought this. Its easy to read and good quality.

I got 2 of the rulers made in Japan. Metal finish is smooth, marks are very uniform and legible. They are perfect for what I needed.

boah ey it is 300mm long

Perfect tool!

If you are looking for an excellent ruler, standard or metric, this is it. I have both the 300 mm and 600 mm. Laser etched numbers and easy to read. Reasonably thick stainless steel, not like the flimsy thin ones at the big box store. These are what I reach out for at my table saw to set the fence distance from the blade (instead of my measuring tape). Awesome product.

The first one of these I ordered was slightly warped and would not lay flat on it's own. It would touch in the middle, but the ends would come up 0.5-1mm on each side. So, I ordered another one. The new one I ordered was different. The first one said Made in China on the packaging, and the new one said Made in Japan on both the package and on the rule itself.The Made in Japan version had Shinwa written in English on it, and the Made in China one had Shinwa written in katakana. If you looked really close, the printing on the Japan version was slightly better, especially with the larger red numbers. The edge on the Chinese version was not as smooth. Another thing to note is that at the 300mm mark they were off about 0.1mm from each other when I lined them up at zero. I didn't bother to check which one was more accurate, because that kind of error is fine for what I'm using this for.BOTH are legitimate Shinwa products. Shinwa has 2 factories in China and one in Japan. Maybe I just got a bad one, but the Chinese version was definitely not as good as the Japanese version. I'm very happy with the Made in Japan version I have now, I returned the slightly warped Chinese version. It's not as nice as my Starrett, but it's 1/5th the price and well worth it. Even though I had problems with the first one I received, I'll buy Shinwa again as they are a great value.

Well made product from Japan. It is hardened stainless, sufficiently deburred, and finished.
