Abstract
Knife assemblies having primary and secondary blades and at least one tab blade. The primary and secondary blades each have a corrugated shape as a result of defining a wave pattern that defines peaks and valleys. The primary and secondary blades each further having upper and lower surfaces, leading and trailing edges, and a depth defined by and between the leading and trailing edges. The upper surface of the primary blade and the lower surface of the secondary blade are complementary so that the secondary blade and the peaks and valleys thereof are able to nest on the primary blade and the peaks and valleys thereof. The secondary blade has at least one tab blade that projects from one of its peaks and is defined by a cut in the peak to form a tab that is bent so that the tab projects from the peak.
