Both a mold blade for forming sipes and the sipe so formed in a tire tread element have three-dimensional portions. In the formed sipe, the three-dimensional portion creates a constant interlocking of the opposing sipe faces. The blade and the sipe have two radially adjacent rows of projections, wherein the projections are separated by a planar section, the planar section having a defined length and width.
