Characters in Hunter × Hunter use a variety of weapons to help them. These weapons include:
Yo-Yos: During the Greed Island story arc, Killua begins using yo-yos made of a special metal alloy in combat. The yo-yos are extremely durable and heavy, weighing 50 kilograms each. They can be used in conjunction with Killua's Hatsu as well. Killua is reluctant to use the yo-yos in combat thus using only his raw physical abilities in order for his opponent to know as little about his combat abilities as possible.
Umbrella: This weapon contains a concealed cane sword, and when it is sheath, the umbrella itself is revealed to be a firearm. It is used by Feitan.
Blowgun: It fires poisoned darts that can paralyze the target for several days. Geretta prefers this traditional weapon to modern firearms.
Pipe: When he doesn't use it to manipulate smoke, Morel Mackernasey uses his pipe as a melee weapon.
