The model of a spinning particle, based on the Kerr-Newman solution with |a|\ensuremath≫m, is discussed. It is shown that the Kerr singular ring can be considered as a string with an orientifold world sheet. The orientifold adds a peculiar extra point to the Kerr ring: the fixed point of the world-sheet parity operator \ensuremathΩ. It is shown that the Kerr string represents a new type of folded string solution taking the form of an open D-string with joined ends which are in circular lightlike motion along the Kerr ring.
