If you need accuracy then you need a Shinwa ruler
These rulers are super high quality and dead on accurate, I've purchased multiples of the 6" and 12" and every one of them was exactly the same accuracy. These are thicker than the cheap chinese/india made levels at your local woodworking store, no flex/bend in them so they lay flat making marking an easier task. The combination of metric and standard is a really nice feature as well, with very crisp and easy to read numbers and lines. The finish is very subtle not shiny/glossy which makes these very nice in bright light, and should hold up for many years to come.

Geeat quality, easy to read
After using this 12 inch Shinwa, I ordered a second one (6 inch) from them as well. These are high quality, accurate, and super easy to read. I like flexible scales for some jobs but really like the rigidness of this scale, since it's easier to pick up from a flat workbench. I wear trifocals and am always jockeying my work pieces around in the light to get a read on a scale. These are so easy to read in most lighting situations, that I may buy several others to have in various work areas. Not a glamorous tool purchase, but once you use them you wonder why you didn't buy one earlier. Highly recommended.

Excellent tool that could use some improvements with clarity of markings for measurements
This is an excellent tool and is weighty and looks very durable. I'll be using it for some time. I'm disappointed that some of the interim markings aren't easier to read and my wife is frustrated with reading it. This should be a slam dunk to be easy to read but is not but I bought it to get a precise and long lasting instrument that I can use and may just require some training to get used to.

Excellent
Ive used this ruler atleast once a day for the past 2 years and ive fallen in love! Incredibly accurate Metric measurements on one side and Imperial on the other. as far as i can tell, the ruler is anodized and then machined down so there isnt any ink that wears away over time. I dont store it in a case or drawer, it has a home just sitting on my desk and it is still in brand new condition. if i received another one of these today im sure it would look exactly the same.

That's not a ruler... THIS is a ruler!
If you are into crafts or other technical hobbies where accurate measurements or even just a good straight-edge are needed... THIS is THE ruler. It lays perfectly flat. It is easy to read (English / Metric sides). The markings are etched into the metal, not just painted. Will probably last a lifetime and then another. It feels sturdy / stiff in the hand, not flimsy. The 1/32 and 1/64 marks on the English side and 1/2-mm marks on the metric side are fantastic for precise measurements. It may seem trivial, but good tools make a big difference... even "just a ruler." Spend a couple of extra dollars on this PRECISION ruler and be done with it. I got the 6" version, too. Well worth it!

Good quality rigid ruler
I'm happy with the quality of this ruler. I like that the zero of the scale is at the edge of the ruler. It's nice and rigid.
