## Questions & Answers

**Q: Can the top portion be slid across?**
A: The top can be slid left and right (to form an "L" ) or removed entirely. It cannot be positioned anywhere else along the ruler.

**Q: Can this T-rule be used with a metal scribe instead of a 5mm pencil?**
A: With a small enough tip it should do just fine. I love mine

**Q: Can this T-rule also be used as a compass (with the T-bar removed) ?**
A: A compass has multiples uses, so if the question is  you could draw circles using this rule the answer is yes, even it will be a little tricky

**Q: Does this allow you to make small lines (I.e. for book folding) or just a dot at the desired measurement?**
A: Yes. You can move the ruler across page to make a line once you find the hole number. I love mine. It is the most accurate I’ve found!
