Winner: Russian granny

1:09 video (Autoplay would not turn off in the embedded version.)

A wolf attacked 56-year-old Aishat Maksudova near her sister’s home in Dagestan in the Northern Caucusus. Maksudova was on her way to repair a fence, and tried to stop a wolf from attacking a calf. The wolf went after her instead, biting her leg and left hand, and knocking her to the ground. Fortunately, Maksudova was able to bring into play the axe she was carrying to repair the fence. She hit the wolf right on the head, splitting its skull and killing it dead.
