A wire saw having improved stress-fatigue characteristics is disclosed. The saw comprises an elongated flexible metallic body having a substantially circular cross section, and a pluraity of cutting segments or blocks of comminuted abrasive in a bonding matrix resiliently mounted on said body in spaced-apart relation to one another in a helical pattern along the length of the body. In a preferred embodiment of the invention, the body has at least one helical ridge along its length. The cutting block bottom surfaces are slotted or grooved to mate with the ridge, and the blocks are mounted on the ridge.
