If you were stranded on an island, what 3 items would you want with you?

If I were stranded on island and I could only have 3 items, I would bring necessary things to survive until someone found me. I would bring some sort of knife, like a multi-purpose knife. The ones that have a knife, compass, matches, and a fish scaler. Also I would like to have someone with me. That way we could get more done faster and easier.
Lastly, I would bring a flint. I would have matches in my multi-purpose knife but I would soon run out. With a flint I would almost always have fire. I could keep warm and also cooking the food I would hunt to survive. Those are the 3 things I would want if I were stranded ona island.
