Gloves: These are special gloves with a unique ability that allows William to transform anything he touches into a weapon capable of nullifying the Devil Fruit user's powers when touched by these weapons.

Throwing Knives: William has dozens of small throwing knives that, through the use of his gloves' ability, can pierce the bodies of those with the Devil Fruit power.

Umbrella: William has an umbrella, which he keeps stored in his Inventory. Using the power of his gloves, William has enhanced this ordinary umbrella to the point where it can deflect and/or withstand Devil Fruit attacks. But it can also be used as a parachute or shield, if necessary.

Cane Sword: William always carries a cane with him, which hides a blade inside. And using the power of his gloves, he becomes capable of cutting the body of any Devil Fruit user. Including the Bara Bara no Mi user.

Rapier: William always carries in his inventory a special rapier, made of an extremely resistant, if not indestructible, metal alloy. Sometimes used in conjunction with the sword hidden in his cane.

Rasaka's Fangs: Two daggers made from Rasaka's fangs. Capable of paralyzing due to the traces of poison. They grant the bleeding effect. William acquired them in his first Dungeon, when he defeated his first BOSS.

Kamish's Wrath: A pair of high-quality daggers created from the sharpest fang of a dragon. Their power is assimilated to the user's strength. In addition, it is an incredible weapon, depending on the user's skill. William obtained them as a reward from a Quest.

Grappling Hook: William carries a pair of hook weapons. He uses them to escape or move around.
