Shinwa 1000 mm Rigid"Zero Glare" Metric Machinist Rule/Rule Scale .5mm & mm

rule scale metric is 1000mm long

Ok, so it's not cheap. I had this in my cart forever before I finally bought it. I know that you'll see reviews on here about some Shinwa products that are made in China and some are made in Japan - whatever. It's Shinwa, its good. I've come to trust this brand. As I'm typing this review, I have other Shinwa products in my cart. It appears to be a company that produces all-around good quality products that you don't have to rob the bank to get. I love Starrett stuff - particularly their vintage stuff - but, damn they're expensive. I'm not a machinist so I don't need precision down to microns. I'm a leather worker so need precision down to millimeters and, so far, Shinwa hasn't let me down. It's good stuff that will last a lifetime, if you take care of it. I'm happy with it.

Very nice ruler for the money. Nothing else on the market comes close within the same price range. Dead on accurate, very sturdy and easy to read. My only complaint is the thickness of it. I use this to Mark fret slots for guitar building so I tape this down to my centerline to ensure it doesn’t move. Because the edge is smooth and the ruler is hefty it’s difficult to line up your mark where you want it.

I’m perfectly satisfied with my Shinwa 1000mm rule. It’s high quality, accurate and precise. I bought this to measure the placement of bridges on the flamenco and classical guitars I am building. These have scale lengths between 604, 650, 654, and 660 mm from the nut. This bridge placement must be done precisely to ensure the correct intonation of the guitar. I have an imperial steel rule from a US company that I use for steel string guitars which was nearly three times as expensive but I could not find a 1000mm rule at this quality at an affordable price except the shinwa - manufactured to meet a standard. I wanted direct mm and .5mm measurement because I don’t want to risk making an error.I have purchased now a complete set of rules from shinwa from 150mm, 300mm, 600mm and 1000mm.I like them very much. It would be great if you made available both rigid and flexible shinwa rules. I had to order the flexible 300mm rule I wanted from Japan.

There are conflicting reviews as to where this is made. My Jan 2024 purchase was made in Japan, see attached photo.The bright surface is easy to read. No unhelpful 1/2 mm marks. Stainless steel is much better for rulers as aluminum has parallax due to its thickness.More generally the Shinwa tools are excellent. I love using them.

Easy to read, not flimsy but not totally rigid and received in good condition inside a cardboard tube that probably needed some newspaper stuffed into each end to prevent movement of the ruler during shipment. The only thing damaged was the ends of the plastic sleeve that took the brunt of movement inside the tube. Recommend this ruler.

This is an excellent, high quality measuring tool. As a woodworking hobbyist, several years ago I started using the metric system for most my measurements. This scale is marked in millimeters and half millimeters. The divisions and the numbers are extremely readable against the satin chrome finish. Because it is marked in millimeters only, rather than millimeters and centimeters or millimeters and inches, it is very easy to use without having to do any mental gymnastics. I also use the smaller Shinwa 150mm and 300mm rules. This 1000mm rule is handy for laying out and for testing edges for straightness. On the back side of these rules is a conversion chart to inch measurements and a metric tap drill chart. In my opinion, the Shinwa rules compare favorably to Starrett and Mitutoyo rules.

As a hobbyist machinist I have always appreciated fine tools and in my eyes this is a fine tool.What classifies this as a fine tool?It feels good in your hand, you can feel the weight and precision.It functions better than you imagined and you know you can rely on it.When I used it to make a cut in some aluminum, I knew that 600mmm was 600mm.The markings are clear and sharp.In this new world of cheap Chinese tools I cringed a little at the price but when I held it in my hands I knew it was worth the price.I will pass it to my grandchildren. I am sure they will enjoy it as much as I do.
