Définition et Signification de "glass cutter"

What is a "glass cutter"?

A glass cutter is a tool used to mark and cut glass sheets. It typically has a small, sharp wheel made of hardened steel or carbide that creates a shallow line on the surface of the glass. To use it, the glass is marked with the wheel along the desired line, creating a weakness that makes it easier to break the glass cleanly along this line. Glass cutters are commonly used in window installation, stained glass projects, and other applications where precise cuts in glass are needed.
