The cutting segment includes a cutting surface for cutting a work piece and a plurality of abrasive particle layers. The abrasive particle layers are disposed perpendicular to a cutting direction. Each of the abrasive layers has a plurality of abrasive particle rows in a width direction of the cutting segment. Each of the abrasive rows has a plurality of abrasive particles arranged in a line. Further, the abrasive layers have a plurality of blank sections therebetween. In the blanks sections, abrasive particles are absent or have a concentration of 70% or less with respect to those in the abrasive rows.
