Twin Strike: When making a single standard attack and wielding two mind blades, the soulknife may attack with both of her mind blades at the normal penalties for two-weapon fighting. She may also utilize this ability when making attacks of opportunity, but not for any other special attacks, unless specifically stated otherwise. The soulknife must be at least 8th level to choose this blade skill.
