Throwing Axes and Daggers (Boomerang Dagger, Axe of Hangard) can be used by Kensai, due to the fact they have a melee component, and return "instantaneously" to the had once throw, which I think the programmers implemented as sort of a spell effect.

This is a bug in my opinion, as the Kensai should not be allowed to use ranged weapons as he's already way powerful (dual to a Thief, in ToB the Use Any Item ability cancels out every disadvantage, a Kensai in Full-Plate, and there's always the dual class to a mage to use Bracers of Defense and Robe of Vecna...) in melee, and dual-classing eliminates many of his disadvantages.
