General Tools Protractor and Angle Finder #39, Stainless Steel, Outside, Inside, Sloped Angles, 0° to 180°

This has been a little lifesaver - I need a portable protractor for odd angles for the work I do, and this has definitely made work a lot easier. Seems to be fairly sturdy and accurate so far. Good value.

I decided to replace the fascia on my house and I have a lot of different angle roof pitches. This little tool probably cut my installation time in half. It is really good quality and does not slip once you secure the angle with the thumb screw. Obviously it cost more than the plastic ones but it is by far superior I highly recommend it

I would purchase again.If you are looking at exactness in number, I'd go another route. It holds an angle we'll -copy an angle just fine. It has some looseness in the hinging.... not bad if you're not picky... (spend more $). As you arrive at a straight line there will be a greater inaccuracy. Engrading: the rules are deeply cut. The compass is much lighter, I believe due to keeping the lines accurate... per photos you will see they are very clean but hard to read for a guy needing bifocals..go figure! They are not printed but Lazerd!! With all that said it's a great tool.Tuneup:First thing I'd do is oil the rivet-hynges.Remove the Thumb nut and flatten out the hole punch on plate back dimond file etc.. it has a sharp ridge. It will add 5bucks to the feel!!Lastly check it with another square tool and compare its exactness.Definatly worth 13$. I'm cuting fire bricks with a recalled Rioby slide saw Haha!The angles need to be right as when tide together they will need to make a good 10 batt circle. So not so much reliant on the angle numbers on tool but tracing existing ones on my fire bricks.Spend a little more on this than the cheaper plastic one. It'll respect you back if you're nice to the tool.

Versatile and easy to use. I had the plastic version which was just as great and sturdy until a friend knicked it with a saw, compromising its accuracy, so I sprung for this metal version and am just as pleased!

Used this tool to measure some angles between structures (concrete, wood). Works great, accurate to within 1 degree. Can lock in the measurement with a thumb screw and read out later.

Works perfect

This is exactly what I needed. I searched elsewhere, but Amazon came through with this all metal, quality construction angle finder. I tend to trust the mechanics of this angle finder over a digital one, and they are about 3-4 times cheaper. I've really enjoyed putting this to good use. It is accurate and enjoyable to use.

Great tool to have just in case.
