The soulknife was one of the coolest ideas in the Expanded Psionics Handbook. Unfortunately, it was one of the weaker executions, spawning a truly astounding number of fixes around the internet (including some from Dreamscarred Press itself).
Largely unaddressed, however, was the need to bring the coolness of the psionic energy blade to other classes. Unaddressed no longer.
Mind Blade Feats isn't about improving your existing soulknife so much as it is about allowing other classes access to the soulknife's signature ability, creating a blade of psychic energy and wrecking havoc with it. Do you invision your paladin smiting his foes with a blade of holy fire? Or maybe you feel your rogue would benefit from a blade that can't be found or taken away by law enforcement agents? Or, perhaps, you want a monk whose ki manifests as physical sais of fury? All can be done easily with this book.
The core of the book consists of fifty feats, including feats that replicate or expand upon soulknife class features, making them available to any class, as well as feats that give other classes' mind blades their own special twists. Also included are specialty levels replacing levels of other classes to more easily integrate mind-blades into them.
