THese are my three assuming that you get found in a week. . .

1. Matches to get a fire started so then you can melt snow to get water and to keep warm.
2. Something like a can to melt water in.
3. Extra clothes to use as shelter, a layer of comfort on the ground, and to keep dry/warm.
It would be nice to have more than three things though.

Nate

something to start a fire with, a good knife, and something to hold and purify water in.

Man, you think I want to be lost in the woods for a week, get a grip!

3 items,
iFINDER® Hunt™ C Handheld GPS

My back pack

And finally and most important item and my insurance policy, “SPOT”(findmespot.com) “MY 911 HELP IS ON THE WAY BABY!

I would want a fire starter, a knife and a wind up radio with the weather channel. You can use a knife to make a bowl and purify water, with the radio atleast you have the voice of someone else around and can tell if there is a storm system coming.

Knife, matches, .22 rifle. With these three tools, survival is a likelihood, and comfort cannot be too hard to scrounge up.

Knife, wind proof lighter, and a shotgun. However, if you get lost in a woods around my area, your just a damned fool and for the sake of humanity it would be best if you went unsaved.

Matches, knife, slingshot.

My metal match (always works for fire)
My wife (always works to keep me warm) :)
My pack (always works to keep me alive) I never leave home without it!!!

Bic lighter, belt knife, my Marlin mdl 39 lever action 22.

1. Machete
2. Multitool
3. A steel cup
Fire can be created multiple natural ways, a steel cup to boil my water, machete to hack wood for shelter and fire, multitool to take care of the rest. Vines & roots can be utilized as rope or twine, spears can be fashioned for hunting, traps can be easily set up with what nature provides, so food is no worry, fire no worry, shelter no worry, water no worry.

I would take first a knife and a pot or pan and flint.

A small hatchet with holster, some method of starting fire:flint, matches,butane lighter etc. and a metal dish for boiling water.

An axe, warm water proof clothes, and matches. You would get WAY more use out of an axe than just a knife.

a sturdy fixed blade,a waterproof/windproof lighter,and a pot to purify water/cook in.
