Calipers

Calipers assist with measuring metals. They can be locked in place at a certain measurement (in inches or in millimeters). The top metal jaws assist with measuring the inside of items, like rings. The bottom jaws measure the outside of items.

Amazon and Gesswein both offer well-made calipers on their websites. Digital calipers with an LCD screen are especially helpful and recommended.
