**Q: what is the smallest measurement that these calipers can measure? Thanks!**
A: The smallest overall measurement between the two outside points is 1.125".

**Q: how thick is the  metal the tool lis made from?**
A: The metal thickness is 1 mm which has been optimized based on significant customer feedback and many trials.  If material is thicker then it becomes too bulky, more difficult to use and heavy.  If the material is thinner, then it is more susceptible to bending and inaccuracy.  Hope this is helpful and thanks for the question.
