Of all the survival tools you will need, a good knife is the only one that is truly indispensable. You can make your shelter, forage for food, use any number of methods to find, purify and store water.
You can even survive a SHTF moment or extended survival situation without a firearm (although it would not be easy.) To accomplish just about everything listed above, however, you will likely need a dependable knife.
In fact, one of the most critical tools in your survival kit is your knife and you should always have one on your person and in your bug-out bag.
If you find yourself, however, without a knife, you do have DIY options. By using discarded saw blades, a paracord, some time grinding and sharpening, you can make this incredibly durable knife.
