What does it mean in Shakespeare to cleave from nave chaps?

In Shakespeare, to "cleave from nave chaps" refers to slicing open someone's head with a weapon, resulting in gaping neck wounds or a split jaw and cheeks. The term "nave" likely comes from "nape," meaning the back of the neck, with "chaps" referring to jaws or cheeks. When spoken, it conjures a horrifying visual of violent injuries caused by brutal weaponry. It was used, especially by Shakespeare, to denote someone being beheaded by an attacker using swords or similar sharp objects.
