cutting form
Japanese: カット基本フォーム
The basic stance is to hold the cutter vertically and pull it toward you at a slight angle.

The term “basic cutting form” refers to the overall technique—including body positioning, grip, posture, and the application of force—used when holding a glass cutter and scoring glass. The way you hold the cutter (such as the pencil grip or overhand grip), how you move your elbow and wrist, the angle and pressure at which you apply the cutter to the glass, and the speed at which you score the glass all form the foundation for a stable cut.
Once you master the correct technique, you’ll be able to score the glass consistently with steady pressure and speed, dramatically reducing the number of mistakes. Ideally, you should apply the cutter perpendicular to the glass (at a 90-degree angle) and maintain a consistent speed and pressure so that a continuous “shar” sound is produced. At first, it’s important to practice repeatedly using scrap glass (cullet) to ingrain the proper form into your muscle memory.
