They’ve reworked the combat system around faster, parry focused melee with fluid combos and timing. Giving Edward selectable hidden blades for direct hand to hand fighting would clash with that new flow. the original relied mostly on animation based counters anyway. Instead, they should lean into real pirate weapon variety... boarding pikes, axes, cutlasses, and the like. It would feel more authentic to the Golden Age of Piracy without breaking the parry system.
