A lockset assembly having an external clutching assembly. The external clutch assembly includes a first spindle connected to a door lever. The door lever rotates to move a latch assembly between a locked and an unlocked position. A clutching torsion spring inter connects the first spindle to a hub. A clock spring inter connects the hub to a cage fixedly attached to a door. A second spindle inserts through the cage inter connects the hub and the latch assembly. Rotation of the door lever with the second spindle moves the latch assembly between an unlocked and locked position. The clutch assembly allows the lever and first spindle to rotate when the second spindle is constrained by the latch assembly in the locked position.
