PURPOSE: A cutting cord of a weeder mixed with grinded stone is provided to improve the efficiency of cutting by mixing the stronger material than resin. The smooth cutting is carried out even in the low speed rotation of the cutting cord. CONSTITUTION: The cutting cord of the weeder mixed with grinded stone includes a grinded stone(1), a cutting cord resin(2) and a center portion(3). Forming is carried out by mixing the cutting cord resin(2) and the grinded stone(1). The center portion(3) of the cutting cord is composed of only resin without mixing the grinded stone. The grinded stone(1) appears outside the resin as the resin is worn away. Smooth cutting of weeds and grass is carried out even if the cutting cord is rotated with the low speed and the efficiency of cutting is improved. And the center portion(3) maintains the tensile strength fully.
