[3.5, fighter feat] Don't Hit Them With The Pointy End

[Flickerdart]

Weapon Ingenuity [Fighter] [Tactical]
You have learned to make attacks with the blunt end of your weapons - that's twice as much weapon, per weapon.
Prerequisites: BAB +6, proficient with all martial weapons, see below
Benefit: When wielding a two-handed weapon, you do not take the -4 penalty to deal nonlethal damage, and gain special options:

Momentum Step: You transfer the momentum from your swing to your body, and slam the pommel of your weapon into your enemy.
Prerequisites: Improved Bull Rush, Strength 13+
When you miss on a melee attack against an opponent, and your attack would also miss their touch AC, you may immediately initiate a free bull rush against that opponent, with a +2 bonus on the check. You may not use this ability on the same target more than once per round.

Pommel Strike: You can make powerful strikes with the hilt of your weapon.
Prerequisites: Improved Two-Weapon Fighting, Dexterity 13+
You may treat any two-handed weapon as a double weapon. The second side is a light weapon that deals bludgeoning damage, and otherwise has the statistics of armour spikes appropriate for your size.
You may make an off-hand attack with the pommel whenever you make a single strike using your weapon's blade (such as an attack of opportunity or a standard action attack). You must decide to use this option before making the attack, and both attacks take a -2 penalty.
Special: If your weapon is already a double weapon, you may deal damage with either the pommel or the second end.

[B][SIZE="3"]Momentum Step: You transfer the momentum from your swing to your body, and slam the pommel of your weapon into your enemy - easily catching them with the blade when they stumble backwards.

I honestly can't picture what you're describing here.

Pommel Strike: You can make powerful strikes with the hilt of your weapon.
Prerequisites: Improved Two-Weapon Fighting, Dexterity 13+
You may treat any two-handed weapon as a double weapon. The second side is a light weapon that deals bludgeoning damage, and otherwise has the statistics of armour spikes appropriate for your size.
You may make an off-hand attack with the pommel whenever you make a single strike using your weapon's blade (such as an attack of opportunity or a standard action attack). You must decide to use this option before making the attack, and both attacks take a -2 penalty. Neither attack may be used as part of a martial maneuver because they require a rigid technique incompatible with this style of fighting.
Special: If your weapon is already a double weapon, you may deal damage with either the pommel or the second end.

The restriction on martial maneuvers seems arbitrary and unnecessary. It's a slight damage boost on TWF for a feat — not all that much.

Also, does this work as per standard for double weapons, or do you get 1.5xStr to damage on the pointy end?
