....That's a mace....It appears as a hilt with a thick metal rod instead of a blade.

Hook Swords-
Curved sword moveset,
R2 attack tears at the enemies shield, depleting half their stamina.
Backwards attack is a throat shot, using the Hook swords hand guard to slash them.
2HR2 parries and unequips the enemies weapon.
The Riposte is a leg slash to bring them to their knees, then a finishing throat slash.
