Review: Great LITTLE tool at a good price - I read all the 1- and 2-star reviews...I'm not sure what the heck those folks were expecting for $11. Yeah, the edges were a bit sharp...I spent two minutes running a fingernail board over the edges, now they're smooth as butter. Yeah, the knurled cap-nut was a bit tight as shipped, but no real problem. Yes, the cap-nut didn't tighten down enough to hold the swing-arm securely (the threaded hole is a bit too short), so I added a tiny washer on top of the compression washer, and now it holds tight. They said the tool they received is inaccurate...but I found it to be within half a degree (or less?) at 25°, 30°, 45°, and 90°. The small size of this protractor doesn't really permit measurement to tighter tolerances than that. One guy said the angle was measured wrong, "...The middle of the ruler and not the edge is where the angle would be accurate." Say WHAT?! As long as the edge of the swing arm is parallel to an imaginary line down the middle (which it IS), then the angle is always going to be the same, whether measured at the middle or EITHER edge of the swing-arm. A couple of folks rated the protractor low because it wouldn't measure inside angles. [sigh] If you want to measure inside angles, buy the right tool. You can get a plastic goniometer for under $8. You can buy a digital angle finder for as little as $17 (although I'd likely shell out twice that and get the Klein). If you want to stay on the cheap, and you already have this little protractor, use a sliding T-bevel (or even just fold a piece of paper) to match the inside angle, then use the protractor to measure the outside angle. But don't criticize a tool because it won't do something it was never intended to do. Look, I'm an amateur woodworker. I buy and fettle old chisels and planes. I use a honing guide to set the initial bevel (25°) for the cutting edges on the chisels and plane irons. We aren't looking for crazy precision, we just want to be consistent and close enough. This little tool is exactly what we need.
Review: Use it for cutting angles on quilting designs...works well and accurately - Use this for cutting accurate angles when making quilting templates. Works great and pretty accurate for the size and price.

### ⭐⭐⭐⭐ Great Idea - But With A Couple Important Caveats
*by J***. on January 25, 2025*

This stainless steel tool arrived in perfect condition. Rust should never be an issue. It's well-made, sturdy and, with care, should last a very long time. The variable-tension hinge is just snug enough to hold tight, while still being easy to adjust. My wife makes custom bike and e-bike frame bags for sale online. In order to perfectly fit the buyer's bike frame, she requires very accurate bike frame angle measurements before cutting the material for the bag. I got her this protractor for Christmas, assuming it would be much easier to use than her little 6" plastic half-circle one. Well, the long arm is great for much-needed longer lines on her paper templates. What's not so great are the angle graduation marks. They are quite hard to see, being super-tiny, thin and light-colored. We find ourselves having to sometimes verify the setting with a magnifying glass, unless we have very bright light. We both have 72-year-old eyes, mind you. If the protractor circle's diameter were just an inch or two bigger, the lines would be wider-spaced and far easier to read (See Photo). Besides those things, the protractor is about 1 degree off. I set it for 90°, and then confirmed the angle using a perfect 90° square. This protractor was actually indicating about 91°, not 90°. The good news is that we now know how far off the intended mark we need to set it, to get the angle we desire. Perhaps the +/- tolerance of just 1° is to be expected in such a low-price entry-type tool. I've found we can live with it, since we only use it occasionally. But if you'll be using your protractor a lot, please keep in mind these issues I've encountered.
