In "A Bunch of Short Dark Hapsburgs," what is the punishment that Miss Daisy devises for the men who attacked her?

Miss Daisy has the men staked to the ground in the shape of a star. After they have suffered in the sun and beg for her to relent, she gives them some food and water to give them some hope. Then she sits down and, in their view, whittles a stick to a point. It is implied that she uses this stick to stab them repeatedly, until they die.
