Then, use a ruler to guide the movement.
The glass cutter is held perfectly straight, then slid across the surface with even pressure.
A single continuous line is sufficient, without going over the same area multiple times.
Once the score is made, the glass can be broken cleanly by hand or with suitable pliers.
An essential tool in glasswork
The glass cutter is used in many areas related to glassmaking. It is particularly useful for:
cutting window panes
making or repairing frames
small carpentry and workshop tasks
It is an indispensable tool for obtaining clean and precise cuts on thin to medium-thickness glass. The traditional glass cutter remains a staple in specialized workshops.
An ancient tool still in use today
This type of glass cutter has existed since the 19th century, when wheel-type models began replacing older diamond-tipped tools. These new versions were simpler to use and, above all, more affordable.
Over time, the design has changed little: a wooden handle, a metal head, and a rotating wheel. This blend of simplicity and efficiency explains why this tool is still used today in some traditional crafts.
Why this object is so intriguing
What makes this tool so fascinating is precisely its mysterious appearance. Without context, it’s difficult to imagine its function. But once explained, everything becomes clear: each element has a specific role in the glass-cutting process.
It also reminds us how enigmatic some everyday professional objects can seem when taken out of their original context.
Ultimately, behind this mysterious object lies an ingenious tool, discreet yet essential in glasswork for generations. The traditional glazier’s tool still testifies today to the artisanal know-how passed down through time.
