ABSTRACT:
A reinforced tool handle and a method of producing the same are provided by which a hollow fiberglass rod is produced with a solid section integrally formed at predetermined stress points. The tool handle of this invention is formed by alternately feeding sections of a light weight core and a relatively strong solid core into the center of a die tube. The alternate cores are uniformly surrounded by resin coated fibers and pulled through the die tube to form a continuous rod having alternate light weight and strong solid cores. The continuous rod can then be cut as desired to form the reinforced tool handle of the present invention.
