I don't know that Psi Warrior is the proper comparison. Looking at the class, its primary ability seems to be accessing either one single +9 equivalent (+5 enhancement, +4 in abilities) weapon or two +8 weapons (+4 enhancement, +4 in abilities which can be re-arranged to suit the situation with a single FRA and whose abilities may be exchanged with 8 hours of meditation (so he could begin with a vicious keen mindblade of wounding and, upon hearing that he will be facing undead on the morrow, change it to a vicious, Lucky, Defending, Psychokynetic mindblade, and then, learning that he will be hunting something else the next week, might switch to a Sundering Bodyfeeder weapon). Given that, a comparison to other classes with weapon abilities (like CW's Samurai or Kensai) might be appropriate.
Curiously, the soulknife gains greater weapon focus but not even normal weapon specialization (without taking four fighter levels). In fact, multiclassing (especially into fighter or rogue) would look very attractive to the mindblade were it not for the fact that he sacrifices his primary class ability: mindblade progression.
Psychic strike is an interesting ability (especially since it seems that the first strike of every combat will be a psychic strike for a soulknife--the ability appears to last forever until used). Somehow I suspect that 5d8 is small potatoes next to a real fighter's iterative attacks at 19th level (and the 5 points of power attack that it would take to equalize their attack bonusses). However, the choice to make the mindblade do int, wis, or cha damage means that a high level soulknife will reduce most foes to mindless hulks quite quickly. There could be some real balance issues to doing five points of int, wis, or charisma damage to a target per round. (Most animals and magical beasts will be incapacitated by a single shot to int, and nearly all other melee foes have a weakness in one of the other stats that means they will only survive two or three hits--not to mention the potential for softening up foes for domination, etc by dealing wisdom damage (so, your wisdom went from 18 to 3; what's your will save with a -8 penalty?) A Soulknife with some way of attacking twice in one round (Snake's Strike, or Expert Tactician) despite taking a Move action to recharge his mind blade could easily deal ten points of int, wis, or cha damage in the first round of combat. Even at high levels, that's likely enough to take most foes down (or at least limit their life expectancy to one more round).
So, while I think that, absent Knife to the Soul, the class is an interesting alternative to Samurai etc (gives up BAB in return for flexibility with weapon powers (don't underestimate the possiblity of dual-wielding wounding weapons), Psychic Strike, and quite a few bonus feats (Free Draw is partial Quickdraw--completed by multiple throw, Bladewind is Whirlwind Attack, Speed of Thought, Weapon Focus, and Greater Weapon Focus) and would have to be playtested in order to be properly evaluated, I strongly suspect that Psychic Strike will be found to be broken in play.

And it's not rogue-like at all, a big disappointment to me. We could have used a "psychic rogue." Instead, we have another "psychic warrior." It's different mechanically, but similar flavor-wise.
Speaking of mechanically, it seems really underpowered. I'd rather have a Greatsword that does 2d6 and strength and a half, rather than a "psi-blade" that does 1d6. Some of the powers (the enhancement bonuses) are just attempts at leveling the playing field with real weapon users, they only get a medium BAB, and the extra d8 damage abilites kind of suck since you can't full attack with them.
But it's OK, once you get to 5th level, you can use it as a bastard sword! Never mind that others could do that at first level. Oh, and for being a Mind Blade you'd think you'd get something like an intelligence bonus to damage or something, wouldn't you? You make a blade, out of your mind and it deals damage based off of your STRENGTH?
