If you were stranded on a deserted island what two items would you take with you and why?

If I were to be stranded on a deserted island I think the two items that I would like to take with me would be a box of matches and some kind of knife that I could use in case I needed it. The matches to me seem to be the most important things to have on you if there was ever a possibility you could find yourself stranded on a deserted island.These two items could be the two things that could help almost anyone to survive on a deserted island. A knife could help a lot in terms of having a supply that could enable to catch fish or cut food and the matches could help when it comes to making a fire that would help cook the food we are catching. These things to me would be the two things I would try to make sure I would take with me in case I ever got stranded on a deserted island.
