Claims1
A fishing rod line guide comprising:
- (a) an inner ring;

- (c) a synthetic resin material molded into said annular space between said rings;
- (d) the outer surface of said inner ring and the inner surface of said outer ring having concave contours wherein said combination of said inner and outer rings and synthetic resin material molded therebetween prevents said inner ring from slipping out of said outer ring, said combination forming a lightweight shock resistant fishing line guide structure.
