How to Make Wilderness Survival Knives

How to Make Wilderness Survival Knives
It's a good idea to always take a knife with you when you venture into the wilderness, but sometimes you'll forget, or lose it along the way. Don't worry, however, because it is possible to make a perfectly serviceable knife from material you can find in nature.


Difficulty: Moderately Challenging

Stone knife

Things You’ll Need:
  • Rocks
  • Bones
Step 1
Survey the area and find a rock or stone that is made of fine-grained pebbles. Pick a rock that is neither too big nor too small. The idea size for making a knife would be about the size of a large egg. Locate another rock that is at least twice as heavy as the first rock.
Step 2
Keep the pebble-grained rock steady on a hard surface. Grasp the rock so that you can keep your fingers out of the way of while still getting a firm hold. Take hold of the heavier rock and firmly strike the egg-sized rock as hard as you can until a piece slices off.
Step 3
Pick through what may be several pieces of rock that have come off until you find a nicely sized one with a sharp edge. You may have to hit the first rock several times or hit several rocks until you get a sharp piece you can safely use for cutting.

Bone knife

Step 1
Locate some bones that can be broken into manageable pieces by smashing them with a rock. You want to get a shard about that is at least 2 or 3 inches long. If you can only find smaller shards, however, that will do, but keep an eye out for more bones as long as you are in need of a knife.
Step 2
Sharpen the bone shard by running a rock against the surface. Shape it so that it resembles a knife blade that is sharp on one side and dull on the other. Try to get the end of the bone pointy in case you need to use it for stabbing fish or game.
Step 3
Make the bone knife more suitable for handling by finding a piece of wood that can be used as a handle. Score a notch in the end of the wood piece so that you can slide it snugly inside. You don't need to take this step, but you will find a survival knife far easier to handle if you can create some kind of handle and you will probably have plenty of appropriate wood pieces available.
