Keen

This ability doubles the threat range of a weapon. Only piercing or slashing weapons can be keen. (If you roll this property randomly for an inappropriate weapon, reroll.) This benefit doesn’t stack with any other effect that expands the threat range of a weapon (such as the keen edgespell or the Improved Critical feat).

KiFocus: The magic weapon serves as a channel for the wielder’s ki, allowing her to use her special kiattacks through the weapon as if they were unarmed attacks. These attacks include the monk’s stunning attack, kistrike, and quivering palm, as well as the Stunning Fist feat. Only melee weapons can have the kifocus ability.
