I believe the bishop may be best, if you get a good grip you can jab someone in the eye with the pointy end. The king might be useful as well.
I would rate the King over the bishop. In most chess sets the tip of the bishop is somewhat rounded, but the cross on the King's crown has some sharp edges.
