Does the article say how he beat off the wolf? :-)
The kayaker fought with the wolf for a few long minutes, suffering bites to his leg and hands as he attempted to pry its jaws apart and put it in a headlock.
He eventually dragged himself and the wolf several metres down the beach to his kayak, removed a 10-cm knife from his life jacket, and repeatedly stabbed the animal.
“He proceeds to start filling this thing with holes in the neck and chest area,” Zucchelli said. “The wolf gives up, gurgling and bleeding, and wanders off into the trees.”
