William Faulkner said this quote
“ The razor hung between his shoulder-blades from a loop of cotton string round his neck inside his shirt. The same motion of the hand which brought the razor forward over his shoulder flipped the blade open and freed it from the cord, the blade opening on until the back edge of it lay across the knuckles of his fist, his thumb pressing the handle into his closing fingers, so that in the second before the half-drawn pistol exploded he actually struck at the white man's throat not with the blade but with a sweeping blow of his fist, following through in the same motion so that not even the first jet of blood touched his hand or arm. ”
