I recently bought myself a Mitutoyo 6″ stainless steel ruler (model 182-105). It has 1/32″ markings on one edge, and 1/64″ markings on the other.
On the other side, it has a metric scale, with mm markings on one edge, and 1/2mm markings on the other. Major markings are in 10mm increments, similar to the inch markings on the side shown in the above photo.
That was actually a surprise – I thought it was an inch-only ruler, and I didn’t research it closely enough before ordering one. Having the metric scale is useful, and encourages me to buy a second one, for my other workspace.
There’s another surprise – the Amazon listing image says “Made in USA,” but mine is marked that it was made in Japan. Mine has the 64ths scale on the top edge, and 32nds scale on the bottom. This doesn’t matter to me, but it’s still important to point out that what you get might not be exactly as pictured.
This isn’t my only “short” ruler, but it’s by far the sturdiest. My other short rulers are of the “flexible pocket ruler” variety. This one is more useful already, because it’s wider, thicker, and very rigid.
It’s easy to read, and the edges are smooth and straight, allowing me to use it as a small straight edge.
I was a little hesitant about the price at first, but I soon forgot about that. This is much more of a precision tool than the plastic and steel 6″ rulers you can find at the office supply store.
I have been buying and using Mitutoyo precision measuring tools and devices for years now, and they have never let me down yet.
