Altered Unarmed Strike (3.5e Feat)
From D&D Wiki
 Altered Unarmed Strike [General]
You can inflict different types of damage with your unarmed strikes.
Prerequisite: Improved Unarmed Strike
Benefit: By default, unarmed strikes are bludgeoning weapons. With this feat, you may cause an unarmed strike to inflict both slashing and bludgeoning damage. You must declare this change before the attack roll is made. Attacks modified in this manner inflict one less point of damage than normal.
