A method of blanking wherein an endless V-shaped groove of desired contour is formed on at least one of the top and bottom sides of a material sheet. The groove is shaped so that the external side thereof is at a right angle to the groove-cut surface of the sheet. A blank having the desired contour is then cut out of the sheet along the right-angled external side of the groove.
