Abstract:
A stone saw blade is a longitudinal rectangular long-bar in shape and has two opposite longitudinal upper top surface (20) and lower bottom surface (20'), two opposite longitudinal lateral surfaces (10, 10'), and two opposite end surfaces (30, 30'), wherein its lower bottom surface (20') is a working surface and its upper top surface (20) is a non-working surface; on each of two longitudinal ends is provided a mounting hole (40) extending through two lateral surfaces (10, 10'); at least one lateral surface (10) close to the lower bottom surface (20') is provided with a guide-fold groove (61, 62, 63) being parallel with the lower bottom surface (20') and extending from one end surface (30) to the other end surface (30'). With the guide-fold groove (61, 62, 63), a simple tool such as a wrench is utilized for clipping a root (71) remained by abrading on the saw blade and turning over it relative to the guide-fold groove, so that the root (71) can crack from the saw blade along the guide-fold groove.
