"The Cowskin" explained to Martin by Dr. Kasim pg.232
Dr. Kasim nodded grimly. "Overseers used to call that type of whip a cowskin. When it came to torturing our ancestors, the cowskin was the white man's favorite tool. Nothing like the bullwhips you see in the so-called slavery movies. A cowskin is shorter and meatier. And no fancy wrist snap needed, so there was no chance of missing or striking lightly. Every swing found its mark and left its mark. Not just on the black man's flesh but on the black man's spirit. And those scars have been passed down from generation to generation."
