TACRAY Titanium Straight Ruler with Both CM & INCH Linear Measure, 19cm Anti-skidding, Multiple-Functional with 1/4" Hexagonal Screwdriver (Black)

I bought this to replace a Starrett stainless steel 6" rule I've been carrying around for years. It doesn't have the fractional precision markings of a Starrett, but I use a caliper or micrometer for that stuff anyway. It's nice and sturdy and makes for a great straightedge. The mm/in markings are perfect for most quick measuring jobs.

I love solid rulers, I love titanium. Great combo. But it does have a few issues - the numbers and hashes aren't super easy to read and you find yourself moving around to get a different light angle. It does have some awesome sticky feet that keep it in place and they STICK. It doesn't move once it's on a surface, which is awesome because you don't need to lean on the ruler to keep it solid anymore. Second, the hex hole for a bit is entirely useless. Ok, MAYBE in a pinch it would be ok, but the bits slide through the hole so you have to hold them in place and whatever you are working on so they should just leave it out or make it circular hole to save on machining costs. Overall, it's a great thing. Expensive for what you get, but the size, the heft and all in all is a great item.

Cheap feeling finish. Markings aren’t clear, fuzzy. Not even certain this is titanium.

Very sturdy, perfect for office and other. I recommend this titanium ruler

One look at the metric side explains what’s wrong with using this to work in inches. Didn’t realize this until I had one, because who would do this intentionally? If you haven’t looked at the picture yet, I’ll explain. You generally want longest marks for the whole units, next longest marks for half units, smaller for quarter units and so on. Meanwhile, this ruler figures differentiating eights and sixteenths, and that’s it. Yes, anyone that passed second grade can figure things out, but in terms of speed and efficiency, it really stinks. And that’s why the metric side looks the way that it does. If you’re working entirely in metric, this would be an awesome ruler. Enjoy!

It's the perfect thickness, with ramped sides, like those old-school rulers you're used to. I've been looking for a titanium ruler exactly like this for SO LONG! This was expensive, but very worth it for this niche item. Lost a star for its, "two pieces of soft plastic sleeves from the back side, to prevent the ruler from sliding/moving when use" which I absolutely HATED the moment I touched it. Two silicone strips, and it took me more than 25 minutes to fully clean off all the sticky gunk from ripping them off, first thing. I need to be able to slide it around on paper, and the silicone strips were the worst design ever. The other thing that helped deduct that one star, is how the markings dont' start at the very edge. Not that big of a deal, but I do prefer to butt the end of the ruler up against things I'm measuring. The etching isn't too deep, but not starting at the edge means I have to strain my eyes to make sure the marking is lined up to whatever I'm measuring. I'd buy it again, because I haven't seen anything else available like this. There's another titanium ruler on Amazon, but it's all silly with holes everywhere, and has an odd and impractical (large/wide) shape for me. The picture I uploaded shows the underside AFTER I removed the two siilicone strips, and labored a while cleaning up the mess left.

Returned immediately as it hurt my eyes.

This ruler is as tough as you would imagine a titanium ruler to be. Happy to find something like this made of titanium. Has some grippy silicone on the bottom that helps it stay put.
