an easy way to kill the Black Knight in Undead Parish is to either lure it out onto the bridge (provided you haven't killed the Drake yet) and let Drake kill it when it flys over the bridge.

the other way is to lower the Knight down the ladder and the passage that leads under the bridge, the Knight will simply walk right of the ledge when it follows you out of the room with the rats in.
