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

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.

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

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.

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

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!

The measurements are very accurate. This is the only choice for architects

I'm really pleased with the quality.
