Not meaning to be facetious, but the answer is to buy a new, longer shafted stick.
have one custom made
Any field hockey stick containing "metal or metallic compounds" is explicitly forbidden and nobody makes them at all. Ice hockey sticks may contain aluminum (a light yet strong metal). THese are usually not completely metal, but have a metal shaft and wooden blade spliced and glued to it. These are not in common use because of how hard they are, and the inaccuracy of the join between blade and shaft.
The shaft and blade.
On the hockey stick, you have the shaft (the part you hold), and the blade (the part that touches the ice). In the blade, you have the Heel, which is the part connected to the shaft. Then you have the toe, which is the tip of the blade, or the end which does not connect to the shaft.

The area near the bottom of the shaft where the width of the shaft decreases as it gets closer to the blade.
