Stranded on a desert island: Which 4 would you choose?

[Hugin]

16. The only two I might substitute from your list... Although, you've chosen wisely.

The primary uses of all of these items are obvious. So, the next step is to think of secondary and tertiary uses of the items and their constituent components.

Right?

1) The handsaw for the knife.

On most desert islands "hard" things or things that out "harden" most of what you will be surrounded by are very rare. Mostly, a knife will be used for cutting and prying. A saw offers this as well, but, it's bigger and would allow for the shaping of more things. Felling palm trees for shelter and fire for instance. A knife is good, but, the saw might be better.

2) Either the hammock or the rubber raft in place of the tarp.

This is a case of the sum of parts may be greater than the whole. Shade would be a big issue. Spending only a short time in direct sunlight and all else becomes moot, because you won't survive. The hammock and the raft can both supply this. In addition the hammock presumably also includes rope which can be used for other things. Now, the raft could also provide rope, shelter, and later water. Initially, your choice of the water purifier is an excellent one. There's a reason they are called desert islands and it's not all because they are deserted. There is no water! The water purifier will last for awhile, but, later when it becomes clogged with use you will have to find some way of purifying water using other methods. A rubber raft could be used to purify water by evaporate distilling. Things to think about.

I hope the first aid kit comes with some antibiotics. Infection is a killer!
