Main-Gauche

The main-gauche (French for 'left hand") is a large dagger with a basket hilt and large quillions. Since most swordsmen use their right hand to wield a sword, this dagger is meant for the left hand, wielded as a defensive weapon when a warrior is using the Two-Weapon Style fighting technique, although it is still considered a stabbing weapon.
The main-gauche is also called a "left-hand dagger."

When used by someone with Main-gauche weapon proficiency, the weapon confers a +1 bonus to attack rolls with the Disarm and Parry maneuvers. Because of its cutlass-like basket hilt, the main-gauche, too, works like an iron gauntlet if the wielder wishes to Punch someone with the hilt rather than slash with the blade.

Main-gauche proficiency is related to, but not identical to, dagger proficiency. Weapon Specialization confers the usual benefits.
