Angle Protractor Angle Finder Ruler Two Arm Stainless Steel Protractor Woodworking Ruler Angle Measure Tool with 0-180 Degrees (30 cm/ 11.8 Inch)

Worked a treat, easy to use if the side is the correct way, but in tight spaces, sometimes couldn't measure angle duento size of the protractor and orientation

Accurate reading and good quality metal. The tightening bolt doesn’t quite tighten it enough to truly lock the position though.

Did what it says.

Great for working out angles. Got to remember that it’s back to front. The thing did come apart once and it got it back together.

Great time saving tool, get one now.

Useless for measuring angles. Ok for transferring but hopeless for measurement. Feels cheap, but it was.

Well made Secure locking Accurate, brought for precision drawing and it's great that once set I can reuse the angle and have faith that it will match the previous marks

What did I use it for? Nothing - I can't read it with any accuracy! If you look at the picture you can see that the width of the '30cm' arm completely obscures the protractor's angle scale precisely where you need to read the scale. In the photograph the angle is something between 92.5 degrees and 109.5 degrees but there is no ability to directly read the scale. Is it me, or is this protractor not fit for purpose?

Good

Nice addition to kit

GOOD PRODUCT, STRONG DESIGN; HOWEVER, USER MUST MAKE MINOR ADJUSTMENTS TO KEEP THE HANDLES IN FIRM POSITION FOR MEASUREMENTS.

Works perfectly and accurate

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.
