Purpose of a Flint Knife

Today, flint knives are a favorite among survival enthusiasts and history buffs alike. They are perfect for demonstrating basic survival skills. It’s an amazing collection of handcrafted tools.

How to Make a Flint Knife?

Making a flint knife involves sourcing the right materials and applying basic stone flaking techniques. Here’s how you can make your own:


  • Flint rock: Look for a piece of flint that fits comfortably in your hand.
  • Leather gloves: Protect your hands from sharp edges.
  • Safety goggles: Always protect your eyes when chipping or breaking stone.
  • Hammerstone: A rounded, hard stone used for knapping the flint.
  • Antler or hardwood: This will be used for the finer shaping.

How To Make A Stone Knife In The Wild? – Flint Knife

1. Prepare Your Workspace:

Have a clear, safe area to work. Lay down a cloth to collect any flint shards.

2. Shape the Flint:

Wear your gloves and goggles. Hold the flint in one hand and the hammerstone in the other. Gently tap the edges of the flint to start shaping your blade. The goal is to flake off thin layers, not to break the rock.

3. Refine the Edge:

Once you have a basic blade shape, use a smaller piece of antler or hardwood to press against the edges. This pressure flaking will help you create a finer, sharper edge along the knife.

4. Smooth the Handle:

You can smooth the handle area by rubbing it against a softer stone or sanding it slightly. This makes it more comfortable to hold.

5. Test and Tune:

Carefully test the sharpness of your blade on a piece of scrap leather or cloth. Be careful, as flint can be extremely sharp. Make any additional adjustments as needed.


Congratulations, you’ve just made your own flint knife! This project not only teaches you about ancient tool making but also equips you with a practical skill that harks back to our survivalist roots. Whether you use it for practical purposes or keep it as a piece of history — your flint knife stands as a testament to human ingenuity and skill. I hope now you can teach your kids if they ask you how to make a flint knife.
