A New Zealand doctor had to use a knife to fight off a shark before swimming to shore, stitching his wounds and rewarding himself with a beer at the local tavern, reported ABC News Tuesday.

The doctor, James Grant, 24, was spear fishing with friends off of South Island, New Zealand Saturday when he felt a tug on his leg.

Grant originally thought it was a friend playing a prank on him before looking down to discover a shark ripping into his leg.

“To be honest it was a bit of an odd reaction. It wasn’t really fear or anything, it was just like: ‘F**k it, I’ve got to try and get this thing off my leg,’” Grant told Radio New Zealand.

Grant told ABC News that he thought the shark was probably attracted to the fish he had just speared.

The flapping fish was still attached to his spear dagger when the shark bit into him. Grant quickly detached the fish with a knife and began fighting off the shark.

“I was just trying to knock that off, and that’s when all this started happening. So it was quite a convenient time actually; I had a knife in my hand so I gave it a good few jabs to try get it off,” said Grant.
