What is a Flint Knife?

Flint knives are blades made out of flintstones.

In this blog post, we shall learn more about these blades, how they are made, their feature and function.

Flint Knife

Flint Stone Defined

The flintstone is a type of stone that is characterized by its hardness and glassy surface. It has been used for the production of bladed tools since the Stone Age, hence explaining why they are also known as stone age blades. Literally, flintstones have colorful exterior finishes due to their low iron content.

Flint Knives Basics

General Description

They are commonly used as survival tools because of their versatility in use. A flintstone blade could be sharpened further to make an even stronger instrument, especially if it is made out of a high-quality flintstone blade.

It is also known to be one of the most durable blades that could still be used even after several centuries.


These blades are made by chiseling away at the flintstone. A hard piece of stone is used so that it can withstand the hammering and carving process to make sure the final product will not be easily breakable and would still retain its sharpness even after years of use.

The first step in making a blade out of a flintstone is debitage. This includes preparation work such as shaping and smoothing the surface of the flintstone followed by removing a large number of flakes from it to make way for further chiseling process. A secondary platform is used, made out of either wood or antler so that producers can have more control over its finishing.

The blade maker then proceeds with the final shaping and polishing by chiseling away at the flintstone. If a scraping action is also used, this could make the blade even sharper.



The blade of the knife is what gives it its cutting edge. It could be thick or thin depending on how the blade maker wanted it to be made.

It is also characterized by a straight edge where the user would hold onto and more often than not, this part of the blade is tapered slightly for a better grip.


A knife’s tang is its extension and this one is also made out of flintstone but it is buried into the handle as a stabilizer. Since these knives are used for survival, there should be no problem most especially during activities that would require the use of both hands such as chopping wood or hammering against something.

Enclosed Hilt

The hilt is the part of the knife that is gripped on to. It could either be wrapped with animal skin or carved out of wood depending on how it was made. If a flintstone blade has an enclosed hilt, then it would mean that the tang is partially exposed and is placed inside of a small hole in the handle.


Designed with various kinds of edges, this tool was widely mainly used for slicing foodstuffs, skinning animals, and scraping things. Users may have held the straight edge while using the curved, sharp edge when scraping.

A few models had serrated blades that were designed specifically to cut wood. Originally, flint knives looked like small, rectangular saws. The handles on a few were ivory, which was reserved only for religious ceremonies.

These knives are commercially sold until now. Present-day buyers use these tools for practical purposes like chopping wood, skinning animals for leather works, and as a defense weapon.

Final Verdict

Truly, flint knives stood the test of time. Having them is like having a piece of history and archeology on your hands.
