The Duck Halberd (ダックハルバード, Dakkuharubādo) is a type of weapon used by warriors of the Duck Clan.
The Duck Halberd is a unique weapon, wielding by the Duck Clan in battle. It is a combination of spear and axe that pierces the target using the target's own inertia and slices downwards with centrifugal force. Part of the axe blade is usually designed to resemble a fish or a squid, representing their home. As such, the weapon represents the Duck Clan's pride, more so than being a simple tool for warfare.
