The Glass Cutter accurately cuts glass sheets by making a shallow score on one side of the surface of the flat glass The scoring makes a split in the surface of the glass which encourages the glass to break along the score Thereby it effortlessly cuts the glass into two pieces This cutter is designed to be used for cutting regular glass rather than tempered glass which may shatter the glass and tend to cut the glass in an undesired direction This six-wheel glass cutter has an anti-slip handle and can be used on glass, diamond, and minerals to provide a perfect score and desired shape to the glass
