STAEDTLER Engineer Aluminum Triangular Scale, 12in Metal Ruler with Color-Coded Grooves, Weather-Resistant, 6 Scales (10-60 Parts per Inch)

Nice scale with base-10 divisions (tenths, 20ths, 30ths, etc.) Works a little better with our base-10 numbering system doesn't it? Fractions ain't my thing. I had a plastic one but it broke scratching my back. Hey, these things do more than just measure. So I needed a stronger one. It looks pretty cool and is different than what you might find on your friend's desk. The markings appear black over the silver-grey aluminum. They look like they are painted on. Not sure how long they will last but I have to assume Staedtler knows what they are doing. Believe it or not, it can still get scratched and marked up. Aluminum can be a bit soft. But it appears definitely stronger than my old plastic one. I use it basically as a ruler at work, using the 1/10 inch scale. I can interpolate between the marks and I think get reasonably close to a nice decimal number, unlike trying to figure out what fraction I have and then convert it to base 10.

I like it! My daughter saw it on the web site and reluctlantly I thought I'd give it a try. Pros: I like it's heft. When you pick it up it feels like a quality tool. The numbers and gradations are very sharp and clear It looks just like the one's we're used to, it just feels like better quality. Probably the edges will not get broken Cons: haven't found any. Summary: Works great, and I just like the feel of the thing.

I use this all the time for Engineering and this has been the best Engineering scale I have bought over the last few years. This has good weight, easy to read numbers, and seems to be very durable.

This is a solid ruler. I didn't notice when ordering that it doesn't have a 1/32 or 1/16 inch scale, which is primarily what I needed. The inch scale is in 10ths, so be aware. Make a great straightedge.

We started buying these extremely durable scales for our field supervisors and formen. With the old plastic scale they would break them by sitting on them. With these they don't break and they have some weight for holding down some papers. We have saved money, time and accuracy using these great tools.

Great scale! the scales are 1:10, 1:20, 1:30, 1:40, 1:50, 1:60 not sure why it didn't list them in the product description. Its has a great feel to it and a nice weight. It'll be nice to be able to drag a pen or pencil along the edge without damaging the edge.

Good build quality. Aluminum build looks and feels durable and the colored center is a nice touch to see easily differentiate the sides. However the numbering is NOT etched into the metal but rather printed/lasered on. However it does look like these will stay on for awhile regardless. Slightly disappointed that its made in China but looks to be a higher grade than the competing products I was looking at on Amazon.

Great ruler, thicker and heavier than knock offs. Worth the couple dollars extra for quality from a name you can trust.

the durability of this rulers frame is unreal.

Muy bueno
