ABSTRACT:
As shown in FIGS.3through7, the first step within the manufacturing process is to mold an elongate body20having a relatively straight structure when compared to the final manipulated ski structure. The elongate body20is preferably comprised of a resilient and flexible material such as but not limited to ultra high molecular weight (UHMW) polyethylene (plastic). It can be appreciated that various other types of resilient and flexible materials may be utilized to construct the elongate body20. Furthermore, the elongate body20may be created utilizing various molding processes such as but not limited to injection molding. Once the elongate body20has solidified, the elongate body20is removed from the respective mold by various conventional removal means.
