ABSTRACT:
In a glass cutter wheel where a blade edge is formed on a disk-shaped wheel, grooves having a predetermined shape are formed at a predetermined pitch in a 1/4 or smaller or 3/4 or smaller blade edge line portion of the entire perimeter of the blade edge. The ratio of the groove portion to the entire perimeter, which largely contributes to a scribing characteristic, is changed such that a desired scribing characteristic can be obtained.
