Its deeply etched, black-filled markings guarantee long-lasting readability, making it a top choice for professionals seeking reliable, precise angle measurements in construction and design.

## Description

This is a new Shinwa stainless steel 19 protractor. Overall length is 8". Base is 3 wide by 2 tall. Markings are deeply etched and black filled for easy readability and long life.

Review: Accurate and easy to use. Worth the money. - Works great. Accurate to about a third of a degree. Good enough for me. Helped me build a wooden box with six sides and no two angles the same. Good action on the tighten screw. Worth the money.
Review: Accurate, nice design and affordable. - The accuracy seems excellent, the markings have maybe 0.1~0.2 degrees inaccuracy at most. The edge is perfectly flush at 180 and 0 degrees. One really nice and innovative feature I noticed is that the indicator arm with the measurement mark is ever so slightly bowed in the vertical plane, like a 0.05~0.1 millimetre and only makes contact with the protractor BEHIND the measuring arrow. This means that throughout use, as long as you don't overtighten the locknut while measuring, it will significantly reduce any wear on the indications and measurement marks since it's not making contact with them. The locknut holds the entire thing together so don't overloosen it, a small 1/4 or 1/3 turn is enough and provides that gap underneath. Very happy. No idea where it was made as the packaging doesn't actually mention on mine, but even if it's made in China it's pretty solid quality. Would have liked to have it made in Japan but oh well. The description is incredibly misleading though, the only Japanese thing about this is the brand behind it. Given that that's the only indication anywhere on this page for where it's made I find that misleading as anyone browsing (like me) would assume it's made there.

## Questions & Answers

**Q: What part of "made in china" and "sold by a company in illinois usa" makes this a "japanese" tool?**
A: I love how the seller answered this question and said, "this is japanese tool. made in japan", but if you look at the pictures of the protractor in the packaging, it clearly says "made in china" at the bottom of the package. XD

**Q: Does the thumb screw on the protractor allow you to tighten the arm to "save" and transfer angles accurately?**
A: Yes, the thumb screw does tighten and allow the user to "secure" the angle. However, the angle can easily get bumped and move on you, just due to the fact there there is no true locking mechanism. I suggest using this protractor to set the angle, then use a different tool to match the angle and transfer it to another work piece. You could certainly use this tool as an all in one stop, but in my experience, you just need to be careful not to bump it, else the angle will change on you.

**Q: Will this work for inside angles?**
A: No.  I use another Shinwa product (the adjustable T Bevel) to duplicate an inside angle and then measure it with protractor.

### ⭐⭐⭐⭐ Not perfectly accurate but pretty good quality otherwise
*by E***W on July 16, 2023*

[I revised my rating to 5 stars. I don't know why I was quibbling over a tiny error that's smaller than the width of the lines and on a par with normal random errors (like from tightening the locking screw). I'm leave the original review below, but now I think this is a 5-star product, especially for the price.] The build quality is good. The markings are nicely engraved. The hole in the arm is not perfectly centered (about .1mm off), leading the reading to be a little off. But I don't expect better than that. it's not that this protractor is made in China (guess where your phone came from). The reason is we paid $13.58 for it. The Starret C19 goes for $114.
