Stone Tools
Prehistoric Age — Self-Learning Material
Why Do Stone Tools Matter?
Stone tools are among the most important archaeological sources for understanding prehistoric societies. Since prehistoric communities left no written records, their tools help us reconstruct technology, subsistence, mobility, adaptation and human behaviour.
They help archaeologists investigate:
- Technological knowledge
- Hunting and food processing
- Woodworking
- Mobility and settlement
- Raw-material exploitation
- Adaptation to different environments
Stone tools become more meaningful when studied with animal bones, plant remains, habitation deposits and other archaeological evidence.
Raw Materials
Prehistoric people selected stones according to their availability and physical properties.
A useful stone needed to produce a sufficiently sharp and durable working edge.
Fine-grained materials such as flint and chert can fracture predictably and are suitable for controlled flaking. Quartzite was widely used in many Indian prehistoric contexts.
Core and Flake
One of the most important concepts in stone-tool technology is the distinction between a core and a flake.
Core
The main block of stone from which pieces are removed.
Flake
A piece deliberately detached from the core.
How Were Stone Tools Made?
Percussion Technique
A core is struck with a hammer to detach flakes.
Hard-Hammer
- Uses a hard hammerstone
- Produces relatively large flakes
- Useful for heavy-duty tools
Soft-Hammer
- May use bone, antler or wood
- Provides greater control
- Can produce thinner flakes
Pressure Flaking
Controlled pressure is applied to remove small flakes. It is useful for precise shaping and edge refinement.
Retouch, Bifacial Working & Prepared Cores
Retouch
Small flakes are removed from an already produced tool or flake to modify its edge.
Bifacial
A tool worked on both faces. Acheulean handaxes are classic examples.
Prepared Core
The core is deliberately shaped before the desired flake is detached. This demonstrates planning and control over stone fracture.
Lower Palaeolithic Technology
The Lower Palaeolithic contains some of the earliest major stone-tool traditions.
Two broad technological traditions are especially useful in Indian prehistoric archaeology:
and
Acheulean bifacial technology
Lower Palaeolithic technology should not be viewed simply as “rough stones”. Producing well-shaped bifacial tools required knowledge of raw material and controlled fracture.
Handaxe, Cleaver and Chopper
Handaxe
Usually bifacially worked, often oval, pear-shaped or pointed.
Cleaver
Characterised particularly by a broad transverse cutting edge.
Chopper
A relatively simple heavy-duty tool produced by flaking an edge of a stone core.
Handaxe → bifacial, often pointed
Cleaver → broad cutting edge
Chopper → relatively simple flaked core tool
Acheulean Tradition
The Acheulean is one of the most important Lower Palaeolithic technological traditions.
Its characteristic large cutting tools include:
- Handaxes
- Cleavers
Acheulean toolmakers often shaped both surfaces of a stone, producing bifacial tools.
Important Indian Contexts
Middle Palaeolithic
Middle Palaeolithic assemblages generally show greater emphasis on flake-based technologies.
Toolmakers increasingly exploited cores to obtain flakes of planned size, shape and thickness.
This reflects increasing control over:
- Core preparation
- Flake production
- Tool shape
- Working edges
Levallois & Prepared-Core Technology
The Levallois technique is an important prepared-core method.
The significance lies in the degree of:
- Planning
- Anticipation
- Control over fracture
Upper Palaeolithic & Blade Technology
The Upper Palaeolithic is associated in many regions with increasing importance of blade-oriented technologies.
Blade
An elongated flake, conventionally considerably longer than it is wide.
Important Forms
- Blades
- Bladelets
- Points
- Burins
- Specialised cutting implements
Blade production could provide long cutting edges while making efficient use of suitable raw material.
Mesolithic: Microliths
The Mesolithic in India is strongly associated with microlithic technology.
Microliths are very small stone implements, often produced from small blades or flakes.
Important Forms
These geometric forms are especially useful in identifying Mesolithic technological traditions.
Composite Tools
Microliths could be incorporated into larger implements made from other materials.
Composite technology allowed small stone components to be combined with organic materials.
Possible Uses
- Hunting weapons
- Cutting implements
- Barbed implements
Mesolithic → Microliths → Composite Technology
Neolithic: Ground & Polished Stone
The Neolithic witnessed extensive use of ground and polished stone implements.
Grinding and polishing could produce smooth surfaces and durable working edges.
Polished axes and adzes were especially useful for woodworking and, in appropriate contexts, forest clearance.
Celt, Axe and Adze
Celt
A general archaeological term frequently used for ground or polished stone implements such as axe- or adze-like tools.
Axe
Primarily designed for chopping.
Adze
A woodworking implement with a differently mounted cutting edge, suited particularly to shaping wood.
Neolithic → Ground/Polished Stone → Axes, Adzes, Celts
Grinding Technology & Food Production
Grinding implements became increasingly important in food-processing economies.
Quern
A stone surface used for grinding or crushing material.
Muller
A handheld stone moved against a grinding surface.
Pestle
Used for pounding or crushing materials.
- Cereals
- Seeds
- Pulses
- Other plant foods
Stone Tools & Prehistoric Economy
How Do Archaeologists Identify Tool Function?
Use-Wear Analysis
Microscopic traces produced during use can help researchers investigate activities such as:
- Cutting
- Scraping
- Woodworking
- Hide processing
- Plant processing
Experimental Archaeology
Researchers reproduce prehistoric tools and use them in controlled activities. The resulting wear can then be compared with archaeological specimens.
What a tool looks like ≠ necessarily what it was used for.

Stone-tool technology reflects changing human abilities to select raw materials, control fracture, manufacture specialised implements and adapt technology to changing economic and environmental conditions.
