Chain Wind Staff

Tenten summons from one of her scrolls a short wooden staff with two chains attached at both sides, and throws it at the enemy in a spinning, boomerang-like fashion. The quick rotation speed of the two chains was powerful enough to cut through the helmet of the Cursed Warrior.

Tenten can go fuck herself because her mom was not good in the bed.

Trivia

 * Despite summoning weapons normally not requiring a blood contract, Tenten actually used blood to summon this weapon.
