Review: Fantastic kit. - Got 2 different sizes. I really like it, just go and buy one or two! I got one when I was 11, in 1985 and I still have it! I decided to get a couple 23cm for kids and a smaller size for bag. Packs a lot of features, the handle is great to lift and change angles. And its sturdy, The new ones are very similar if not the same as the old one.
Review: Nice sturdy set square with useful measures. Can be used with a blade - I love this set square. It's all I wanted except for the size. If they made one which fitted in my A5 note book and without the handle it would be 100% perfect. I love the sturdiness and the measures. It's SO much more useful than just a ruler. The tough plastic means it can be used with a cutting blade too which makes it an all round great item. Let me know when you make a notebook friendly version and I'll buy it.

## Questions & Answers

**Q: Is the ‘0’ flush with the edge of the set squares?**
A: No, there is a central, marked zero and the values move left and right from that.

**Q: Why does this have arrows at 7°, 42° and 75°?**
A: I have no idea what this means, but here is the answer you seek! (from wiki).
'Some variants have extra markings at angles of 7° and 42° (138° and 173°) in addition to the normal 45° and 90° markings to ease dimetric axonometry per ISO 5456-3'

**Q: What are the angles for the triangles?**
A: 45,45,90 equilateral triangle and a 60,30,90 set square

**Q: What angles are the 30cm and 20cm set square ?**
A: Angles are measured in degrees not centimetres. The smallest angle is 30 degrees at the pointed end of the longer triangle.

### ⭐⭐⭐⭐⭐ Awesome awesome awesome
*by J***H on 31 October 2020*

Just perfect for any need. I didn’t realise it would before purchasing, but it actually changed the way I draw straight lines. Saves so much time and hassle. With the handle it’s so much easier to just pick up and swap angles and draw lines with the long edge. It’s also a protractor which is very useful. Amazing price and such great design and quality.
