Quick Answer
Arrowheads and blades have distinct differences in terms of design, functionality, and production methods. Arrowheads are typically small, pointed, and designed for hunting or self-defense, while blades are longer, broader, and often used for various tasks such as cutting, slicing, or chopping. These differences are reflected in their manufacturing processes.
Design and Functionality
When it comes to flintknapping, the primary goal of arrowheads is to create a projectile that can penetrate or cause damage upon impact. As such, they are often designed with a narrow, pointed shape and a sharp, aerodynamic edge. Blades, on the other hand, are used for various tasks such as cutting, slicing, or chopping. They are typically longer and broader than arrowheads, with a flat or slightly curved edge.
Production Methods
The production methods for arrowheads and blades differ significantly. Arrowheads are typically made using a combination of percussion and pressure flaking techniques. Percussion involves striking the stone with a hammer or punch to remove small flakes, while pressure flaking involves using a pressure flaker or a piece of bone to carefully remove tiny flakes and shape the edge. Blades, due to their larger size and more complex shape, often require a more intricate combination of percussion and pressure flaking, as well as the use of specialized tools such as a billet or a drawknife.
Tips for the Modern Flintknapper
If you’re attempting to make your own arrowheads or blades, here are a few tips to keep in mind. First, choose a high-quality piece of flint or chert that is dense and easy to work with. Second, use the right tools for the job - a good hammer or punch can make all the difference when it comes to percussion flaking. Finally, be patient and take your time - flintknapping is a delicate and precise art that requires attention to detail and a steady hand.
