Stranded on a desert island

If I was stranded on a desert island I would bring a fire starter and knife. I would bring a fire starter so I will always be able to start a fire and create warmth, light in the darkness, and cook the food I am able to eat.  I would also bring a knife because I can create other weapons for fishing, protection, housing, and creating other weapons.  I will be able to survive as long as I want to with just these two items.  Other items would be a luxury and not necessarily required for survival.
