1. A toy top, comprising: a toy top body having a substantially conical shape with a first narrow end, a second, opposite, broader end, and an axis of rotation, anda shaft extending from the first end of the toy top body, having an axis which corresponds to the axis of rotation of the toy top, and including a spinning surface upon which the toy top spins on a playing surface on the axis of rotation,wherein the shaft includes a plurality of spaced projections extending in the direction of the axis of the shaft, each having a tip and sides extending from the tip,wherein the tips define the spinning surface,wherein the tip of each of the projections can wear due to friction with the playing surface, or each projection can break off from the shaft due to impact with an object, to redefine the spinning surface, andwherein the projections are arranged along concentric circles that are centered on the axis of the shaft. 2. The toy top according to claim 1, wherein the projections arranged along the concentric circles are configured such that at least one of an inner projection extends farther from the toy top than at least one of an outer projection. 3. The toy top according to claim 1, wherein at least one of the projections has a triangular cross section. 4. The toy top according to claim 1, wherein at least one of the projections has a polygonal cross section. 5. The toy top according to claim 1, wherein at least one of the projections has a circular cross section. 6. The toy top according to claim 1, wherein at least one of the projections has an oval cross section. 7. The toy top according to claim 1, wherein the projections are made of resin. 8. The toy top according to claim 1, wherein the toy top body is made of a first material, and the plurality of projections is made of a second, relatively softer material. 9. The toy top according to claim 1, wherein the toy top is made of a metal, and the plurality of projections is made of a second, relatively softer metal. 10. The toy top according to claim 1, wherein the toy top is made of a resin, and the plurality of projections is made of a second, relatively softer resin. 11. A toy top, comprising: a toy top body having a substantially conical shape with a first narrow end, a second, opposite, broader end and an axis of rotation; anda shaft extending from the first end of the toy top body, having an axis which corresponds to the axis of rotation of the toy top, and including a spinning surface upon which the toy top spins on a playing surface on the axis of rotation,wherein the shaft includes a plurality of spaced projections extending in the direction of the axis of the shaft, each having a tip and sides extending from the tip,wherein the tips define the spinning surface,wherein the tip of each of the projections can wear due to friction with the playing surface, or each projection can break off from the shaft due to impact with an object, to redefine the spinning surface, andwherein at least one of the plurality of projections extends farther from the toy top than at least another of the plurality of projections. 12. The toy top according to claim 11, wherein the projections are arranged along concentric circles that are centered on the axis of the shaft. 13. The toy top according to claim 11, wherein the toy top body is made of a first material, and the plurality of projections is made of a second, relatively softer material. 14. The toy top according to claim 13, wherein the first material is a resin and the second material is a resin. 15. A toy top, comprising: a toy top body having a substantially conical shape with a first narrow end, a second, opposite, broader end and an axis of rotation; anda shaft extending from the first end of the toy top body, having an axis which corresponds to the axis of rotation of the toy top, and including a spinning surface upon which the toy top spins on a playing surface on the axis of rotation,wherein the shaft includes a plurality of spaced projections extending in the direction of the axis of the shaft, each having a tip and sides extending from the tip,wherein the tips define the spinning surface,wherein the tip of each of the projections can wear due to friction with the playing surface, or each projection can break off from the shaft due to impact with an object, to redefine the spinning surface,wherein the toy top body is made of a first material, and the plurality of projections is made of a second, relatively softer material to allow the projections to wear or break more easily than the toy top body. 16. The toy top according to claim 15, wherein the first material is a resin and the second material is a resin. 17. The toy top as recited in claim 15, wherein at least one of the plurality of projections extends farther from the toy top than at least other of the plurality of projections. 18. The toy top according to claim 17, wherein the projections are arranged along concentric circles that are centered on the axis of the shaft.
