chert (countable and uncountable, plural cherts)

2. (countable) A flint-like tool made from chert.

Usage notes

Generally, in mineralogy and geology, a chert does not have a conchoidal fracture. In North American archeology the term chert occasionally is still used for various siliceous minerals (including flint) that have a conchoidal fracture; this leads to confusion between the terms flint and chert in some archeology texts.
