发明名称 Beveled end pieces for an arrow
摘要 Example nocks, arrowheads and/or arrowhead inserts include a tapered annular flange axially engaging a correspondingly tapered edge on a tubular arrow shaft. The tapered flange and edge help prevent the end of tubular arrow shaft from deforming radially outward when substantial axial force is applied to the nock, arrowhead and/or arrowhead insert.
