A disk-shaped throwing implement comprising a central circular part provided with identical wings which are symmetrically distributed around its circumference is disclosed. Each of the wings comprises two sections or areas one of which is substantially planar and lying within the same plane as that of the central part, with the second wing section being curved or bent and projecting at an angle to the first wing section. The free rim of the first wing section being curved or bent in a direction opposite to the bend or curvature of the second wing section. One embodiment of the invention discloses that, additionally, the free outer rim of the second wing section is curved or bent in a direction opposite to the bend or curvature of the free rim of the first wing section.

A throwing disk comprising: (a) a substantially planar, central ring part having an aperture, an inner edge, and an outer circumference; (b) a plurality of wings distributed about said outer circumference; each of said wings comprising: (1) a substantially planar first wing section directly adjoining said outer circumference and being substantially co-planar with said central ring part; (2) a second wing section with a free outer rim, said second wing section adjoining said first wing section and extending, with respect to said outer circumference, essentially in a peripheral direction and being bent with respect to said first wing section; and (3) a further free rim adjoining the first wing section; wherein: (i) said second wing section is bent in such manner that said bend is located along an edge of said first wing section which forms an angle of between 40°-50°with a chord of the outer circumference of said central ring portion, said cord originating at the ending point of the first wing section and terminating at the starting point of the first wing section with respect to said outer circumference of the central ring part and; (ii) said further free rim of said first wing section is bent in a direction opposite to the bend of said second wing section such that when said central ring part is in a horizontal position, the bends of said free rim and said second wing section extend in respective upward and downward directions.
