A molding element for molding and vulcanizing a tire tread. This tread comprises a tread surface intended to come into contact with the ground when this tire is running. This molding element comprises a molding surface intended to mold part of the tire tread surface and a blade of length L and of height Hc intended to mold a sipe or a groove in the tread, the blade comprising a rounded end extending along the length of the blade in a direction of extension X. The molding element comprises two cutting means positioned on either side of the blade at a certain distance from this blade. Each cutting means comprises, at one end, an alternation of peaks and troughs extending in this direction of extension X. The distance of these peaks in relation to the molding surface is greater than or equal to the height Hc of the blade.
