Three items taken on an island

If I must choose three things when I prepare to land on an island where there are only some trees.I think the first thing I shoud take is a hotchet which can help me to make fire to toast the food and light in the forest.The second item which I often use is net to catch some fish.The third object I should take is a gun which is full of ballets.If there us a ship.I can shoot to attract them that I can leave from the island.
