Take 3 things on the island

In the future, if I am on the island which is surrounded by a sea alone. I will take 3 things with me.

The first thing is a swiss knife, which is very useful including many kinds of knives, it not only can protect me if some dangerous animals attrack me but also can help me to make something for living, such as chopping some branches to make a campfire, cutting some leaves to make a bed for sleeping and so on.

Second, I will take some flint stones, which I can use to make fire and they also fire in damp conditions. These stones are better than lighters and matches in this way. And it is also easy to take. I can take so much of them.

At last, I want to take enough food and water. Although, these foods can't keep for a long time. I think they can help me for a few days. I can find some plants and little animals which aren't bad for our health and can be taken on this island or in this sea during these days.

If I take these things on this island, I think I can live on it by myself for a long time.
