Im pretty sure the glaive i have seen had a wood handle same as a spear would.
wood bond:
Your mystical bond with wood is such that your weapons become an extension of your body. You gain a +1 competence bonus on attack rolls when wielding a weapon made of or mostly consisting of wood (such as a bow, club, quarterstaff, or spear). This bonus increases by +1 at 5th level and every five levels thereafter.
A glaive is going to have a higher metal-wood ratio than a spear, but certainly more wood than metal. There's no answer to this question really, besides "ask your GM," but my personal ruling would be no.
