PROBLEM TO BE SOLVED: To improve folding endurance strength of an integrated tie bar cutting die 01 by making the comb-teeth section 04 of the die 01 grindable and, in addition, to improve the economics and productivity of the die 01, by making the wear resistance of the die 01 improved and making ultrafine carbide particles usable. SOLUTION: In order to made the comb-teeth section 4 of the integrated tie bar cutting die 01 grindable, the section 04 is formed at a penetrated portion 11, where the groove 02 of the die 01 formed in the horizontal direction 10 on the upper surface 08 of the die 01 and on a counterbore 07.
