Review: Quality scale with tenths, 20ths, etc. made from aluminum - 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. Review: It's great - 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. ## Features - BUILT TO LAST - Made from solid aluminum, this engineer scale stands up to daily wear and harsh weather.
