Percussion flaking is a technique used to create stone tools by striking a piece of stone with another harder stone or bone in order to remove flakes, or thin pieces of the stone, from the surface. This technique was widely used in the past by human cultures around the world and is still used today in certain traditional contexts.

Percussion flaking has a long history, with evidence of its use dating back to the Lower Paleolithic period, around 2.6 million years ago. It was a popular method of tool-making among early human cultures because it was relatively simple and required only basic materials, such as a hammerstone and a core, or the piece of stone from which flakes were removed.

The process of percussion flaking begins with the selection of a suitable hammerstone and a core. The hammerstone should be made of a harder material than the core, such as quartz or flint, in order to effectively remove flakes. The core is then prepared by shaping and grinding it into the desired shape, such as a blade or a spear point.

Once the core is prepared, the flaker begins the process of removing flakes by striking the surface of the core with the hammerstone at a specific angle and with a specific amount of force. This causes the surface of the core to break and detach in the form of a flake. The flaker can then shape and sharpen the flake by removing additional flakes from the edges and points.

Percussion flaking was an important technique for the production of stone tools because it allowed early human cultures to create a wide variety of tools for different purposes, such as cutting, scraping, and hunting. It was also a key factor in the development of complex stone tool-making techniques, such as pressure flaking, which allowed for even finer control over the shape and size of the flakes.

Today, percussion flaking is still used by traditional cultures around the world, including indigenous groups in North and South America, Africa, and Asia. It is also used by modern flintknappers, or people who recreate stone tools using traditional techniques, for educational and recreational purposes.

In conclusion, percussion flaking is a technique that has played a significant role in the history of human tool-making and continues to be used in traditional contexts today. It is a simple yet effective method of creating stone tools that has allowed human cultures to survive and thrive throughout the ages.

Percussion Flaking Even Before Stone Age: Bone Tools Crafted From Elephant Remains Challenges Understanding of Early Humans

As you will soon see the fractures of the struck material will break in a predictable manner. You can also tap the stone and listen to the pitch. This is called a Hertzian Cone see figure 1. What do archaeologists learn from stone tools, other than how people made them? This is done after the initial creation of the preform with the use of percussion flaking. This can be done by using a large hammering tool.

Lithic reduction

Archaeologists have found preserved foreshafts in rock shelters and caves. The assembly is cushioned on pieces of leather. You can view pressure flaking sort of like whittling the rock into its final shape. Ideally the grinding stone will be softer than the flake. Percussion flaking Percussion flaking is the act of striking your material to break it apart in a controlled manner. These artifacts in turn broadcast a shared sense of human ingenuity, cleverness, and craftsmanship. Possibly, they made these stunning bone tools because of the large number of elephant bones present in their territory compared to other groups.

The foreshaft, in turn, socketed into the front end of the arrow shaft or atlatl dart. Percussion Flaking was very essential to the Oldowans in that, they needed the tools for hunting and cutting up of animals into manageable pieces. To prevent your work from being confused as archaeological evidence, always add a penny or two to your pile of debitage and be sure to sign and date your completed work with a diamond-tipped pen. These ancient tools were determined to date back sometime around 400,000 years ago. The pressure flaking tool will wear down over time so periodically sharpen it while making your tool. French researchers call the first option façonnage, and the second option debitage.

Indirect Percussion Flaking

This style of pressure flaking produced tools without a defined central ridge. Safety It may surprise you to know that in the past when flint knapping could be a person's profession that many of them died from silicosis. Items of material culture are no exception as a nearly countless suite of artifacts were manufactured by prehistoric native Americans through the addition, combination and subtraction of raw materials such as stone, clay, bone, shell, wood and plant fibers. Percussion Flaking Percussion flaking is the act of striking your material to break it apart in a controlled manner. For a different effect, the face could be constricted—such as held against the palm of the hand—which increased the stiffness of the detaching flake, encouraging it to roll over the centreline before terminating. The tools Mike was using at that time has changed slightly since then but the basic procedure has not.

It has been shown that stages in the lithic reduction sequence may be misleading and that a better way to assess the data is by looking at it as a continuum. In short it is more precise. This is called a Hertzian Cone see figure 1. Understanding Stone Tools and Archaeological Sites. So if the Native Americans made mistakes, don't get discouraged when you do as well.

Sort of like shattering glass but also fine grained so that the stone reacts to your strikes in a consistent manner. You can also tap the stone and listen to the pitch. The findings contain 98 pieces of tools developed from elephant bones. In most cases, the amount of pressure applied to the objective piece in soft-hammer percussion is not enough for the formation of a typical conchoidal fracture. Some modern hobbyists make use of indirect percussion almost exclusively, with little or no pressure flaking to finish their work.

So, one core rock will yield a number of flakes for various tools. You can view pressure flaking sort of like whittling the rock into its final shape. There are two elements in this index: 't' and 'T'. The central ridge was enhanced when matched by flakes removed from the opposite edge. The history of human technology began with percussion flaking and some researchers have suggested that the evolution of the human hand and arm was driven in part by the need to percussion-flake stone into tools. Assessing these patterns helps archaeologists reconstruct ancient trade and travel routes.

Pressure flaking is the most difficult part of a flint knapping. You now have a completed arrowhead. These artifacts link us to technology and techniques of many cultures, both modern and ancient. Shoes and sturdy pants are also things I would not consider doing without. Since the early eighties, flintknapping as a hobby has been growing at an expediential rate. The toolmaker could either flake the core into the tool they wanted or they could shape the core in such a way that the flake removed from it had the properties that they were after. These artifacts link us to technology and techniques of many cultures, both modern and ancient.

Percussion vs. Pressure Flaking

percussion flaking

Pressure flaking is the removal of stone from the edges with a pointed implement. A flake generally has very sharp edges, making it useful for cutting, scraping, and carving. The percussion flaking method is known to be used on stones, leaving the experts perplexed with the findings that were much older than the stone age. Gloves, shoes, and sturdy pants are also highly recommended. You can expect to ruin a number of flakes while learning. But depending on your rock you are trying to knap you might need a more powerful tool such as a hand held stone.

Hence punches were mostly made from antler, although horn, bone, or wood may have also been used. In a uniform material, the force from a strike moves out from the point of impact in a cone shape that is roughly 100 degrees wide. Lithics: Macroscopic Approaches to Analysis. To break apart and shape your material you will be using some simple tools for percussion and pressure flaking. Hunter-gatherers relied upon this key wilderness survival skill to create important tools and hunting implements. So to make this platform you will strike your core rock and it will fracture at roughly a 50 degree angle from the direction of impact. The percussion flaking method is known to be used on stones, leaving the experts perplexed with the findings that were much older than the stone age.
