[General Fantasy] What makes a vorpal weapon vorpal? Is it the material from which it’s made? Is it its manner of making? Is it the enchantments applied to it? The skill of the wielder? Or some combination of the above?

The implication of the vorpal sword is that it is sharp enough to easily cut off an opponent's head; this idea of "extreme sharpness" is carried on in *Dungeons & Dragons*, where vorpal weapons are normally enchanted, but not always - the implication being it is the *sharpness* that gives the vorpal quality, not the necessarily enchantment itself. No particular material is specified for the blade, and no reference made to particular skill of the wielder - you might compare Death's scythe in the Discworld, which "exudes an aura of sharpness that extends several inches from the actual blade."
