STAEDTLER Professional Triangular Scale Ruler - 12in Metal Architectural Scale with High-Contrast Etched Markings, 6 Imperial Scales for Drafting & Blueprint Reading

I carry this in the jobsite while reading scaled drawings. The aluminum body makes it perfect for use in this context because it can take a lot more scratches, beating and bending before breaking. I've tried using cheaper plastic scales but these always broke or the paint wore out quickly. The added weight also makes is a great paper holder when reading drawings outside.

Perfect, just what my son needed for school

The old style metal tri ruler, love it, build quality is top notch, its solid like you remember them being, numbers are easy to read... this is the one.

Corners were slightly sharp. I appreciate that there was some effort to make sure that they weren’t extremely pointed ends. However I did have to sand them down to make them more comfortable for my personal preference. Other than that it is a very quality scale and seems very durable. I would definitely recommend.

All I use is the quarter inch scale. Works great for my purposes.

I've always got a scale in my desk even though most of my measuring is done with a roll-o-meter these days. Sometimes, you just need to be exact, and occasionally there is still the need to do some manual drafting. I love the "heft" of this product, it just feels good in my hand. And when I'm drafting I don't have to work about small nicks on the edge like I'd get with a plastic scale. Let's face it, if you're buying a scale, you know you're still going to be using the same one 10 years from now. Spend a little more money and get a product that you'll *love* owning!

Nice scale. It's heavier than the cheap plastic scales (which I like). It looks and feels like it will withstand getting tossed in the laptop bag and carted around for use.

The scale is great, but it arrived damaged and won't lay flat on the corner that was smashed. It seems to have needed a lot of force for this to happen, as it is solid, lightweight metal. I'm using it for class, so it's not bad enough to replace, but it is disappointing.

Its a great sturdy ruler that has every scale that you need on the fly. It has some weight on it but not that much, just enough to have a nice feel to use it.

Quality ruler.

Had a plastic one for 25 years and lost it . Bought a metal one and couldn't be happier. Well made , very sturdy and precise. Love the weight of it.

Best scale ruler yet. Metal is much better than the plastic version.
