If she has proper grip with the large sharp knife and has some muscles, yes.

Another Answer

There are many, many variables involved in such an encounter. The large cat is designed to hunt. It has long sharp claws attached to powerful limbs, as well as long sharp teeth attached to powerful jaws. If you can avoid these items coming into contact with your body during the encounter, putting you into shock, you have a chance to impart killing damage. Of course you have to know what damage will kill the animal as well. Anyone can kill a large cat with a foot long sharp stick if inserted through one eye deep into the brain. Being close enough, fast enough, and accurate enough to push the stick through the eye into the brain is the hard part.
