Multipurpose weapon- eh! The various Indo-Persian war axes with a spike are also commonly called zaghnal. War axe battlefield use across all regions/cultures has been largely and erroneously underreported in history with greater emphasis on the sword.
Most spiked zaghnals, aka crow beak axes, have an incurving point. My example posted is much less common with the recurving point. But, IMO, there is a very good reason for that recurve. Sink an incurving point into an opponent… then try to pull it out with the handle. The geometry is all wrong. The geometry of the recurved point would not hinder retrieval. Same reasoning as why the short shafted thrusting spears, like those of the Zulu, have no barbed or squared off rear profile on the spear head.
