Brandon, Florida - Hillsborough deputies say 42-year-old Annette Smith was angry at her sister, so she sliced her with a samurai sword.
Smith was arrested at her Brandon home early Wednesday morning.
Authorities say Smith was waving the sword around and yelling at her sister when she made a 4-inch cut into her sister's abdomen.
The arrest affidavit states the sister tried to grab the sword, and was cut on her left fingers and hand. She has a severed tendon in her middle finger that will require surgery.
Smith remains in the Orient Road jail without bail. She's been charged with assault and battery with a deadly weapon.
