ABSTRACT:
A blade material cutting device for producing a blade material used as a punching blade. Included are: a stationary blade part having a pair of front and rear support faces on which a strip plate part and a blade edge part of the blade material are to be overlaid, and which are separated from each other by a gap in a feeding direction of the blade material; a pair of opposed front and rear stationary edges which are disposed in the pair of support faces; a movable blade part which moves into and out of the mutual gap between the pair of support faces; and a pair of front and rear movable edges which are disposed in the movable blade part. When the blade material is overlaid on the support faces and the movable blade part is moved, a disposal portion of the blade material is cut away, and the shapes of the front and rear ends of the blade material are not bent but are maintained in their original shape.
