The user's slashing attacks travel forward from the blade as if they where a projectile. The projection also apply each weapon's specific properties, possibly enhanced further by the user's own abilities: infusions (fire, electricity, ice, light, darkness, etc.), effects on touch (death, disintegration, petrification, absorption, corruption), and various others. Rather than simply creating razor-sharp air currents via movement pressure, this actually act as an extension of the blade, carrying its sharpness and properties to a range longer than the physical weapon.
