Two-Weapon Fighting: Benefit: Your penalties on attack rolls for fighting with two weapons are reduced. The penalty for your primary hand lessens by 2 and the one for your off hand lessens by 6. See Two-Weapon Fighting in Combat.
Normal: If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon. When fighting in this way you suffer a –6 penalty with your regular attack or attacks with your primary hand and a –10 penalty to the attack with your off hand. If your off-hand weapon is light, the penalties are reduced by 2 each. An unarmed strike is always considered light.
Double Slice (1st lvl): Benefit: Add your Strength bonus to damage rolls made with your off-hand weapon.
Normal: You normally add only half of your Strength modifier to damage rolls made with a weapon wielded in your off-hand.
Weapon Focus(Fighter bonus - 1st lvl): Benefit: You gain a +1 bonus on all attack rolls you make using the selected weapon. kukri
Sneak Attack (Rogue - 1st lvl): If a rogue can catch an opponent when he is unable to defend himself effectively from her attack, she can strike a vital spot for extra damage.
The rogue's attack deals extra damage anytime her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target. This extra damage is 1d6 at 1st level, and increases by 1d6 every two rogue levels thereafter. Should the rogue score a critical hit with a sneak attack, this extra damage is not multiplied. Ranged attacks can count as sneak attacks only if the target is within 30 feet.
With a weapon that deals nonlethal damage (like a sap, whip, or an unarmed strike), a rogue can make a sneak attack that deals nonlethal damage instead of lethal damage. She cannot use a weapon that deals lethal damage to deal nonlethal damage in a sneak attack, not even with the usual –4 penalty.
The rogue must be able to see the target well enough to pick out a vital spot and must be able to reach such a spot. A rogue cannot sneak attack while striking a creature with concealment.
Knife Master: Sneak Stab (Ex): A knife master focuses her ability to deal sneak attack damage with daggers and similar weapons to such a degree that she can deal more sneak attack damage with those weapons at the expense of sneak attacks with other weapons. When she makes a sneak attack with a dagger, kerambit, kukri, punching daggers, starknife, or swordbreaker dagger (Advanced Player's Guide 178), she uses d8s to roll sneak attack damage instead of d6s. For sneak attacks with all other weapons, she uses d4s instead of d6s. This ability is identical in all other ways to sneak attack, and supplements that ability.
Hidden Blade (Knife Master - 1st lvl): A knife master adds 1/2 her level on Sleight of Hand checks made to conceal a light blade. This ability replaces trapfinding.
Pressure Points* (Rogue Talent lvl 2 rogue/Ninja talent): A ninja with this trick can strike at an opponent's vital pressure points, causing weakness and intense pain. Whenever the ninja deals sneak attack damage, she also deals 1 point of Strength or Dexterity damage, decided by the ninja. Unlike normal ability damage, this damage can be healed by a DC 15 Heal check. Each successful check heals 1 point of damage caused by this trick. A ninja with this trick receives a +10 insight bonus on this Heal check.
Evasion (Rogue 2nd lvl): At 2nd level and higher, a rogue can avoid even magical and unusual attacks with great agility. If she makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage. Evasion can be used only if the rogue is wearing light armor or no armor. A helpless rogue does not gain the benefit of evasion.
Dodge (3rd lvl): You gain a +1 dodge bonus to your AC. A condition that makes you lose your Dex bonus to AC also makes you lose the benefits of this feat.
