Concept:
Stone tool making techniques in prehistoric archaeology are classified according to:
• Method of striking,
• Control over flake removal,
• Tool shaping process,
• Nature of percussion.
Flaking techniques were extremely important during the Paleolithic period because early humans depended heavily on stone tools for:
• Hunting,
• Cutting,
• Scraping,
• Food processing,
• Defense.
Step 1: Understanding Free Flaking Technique.
Free flaking refers to:
\[
\text{Removal of flakes by striking freely with a hammer stone}
\]
This technique does not involve:
• Fixed support,
• Controlled pressure shaping,
• Stationary anvils.
Instead, flakes are detached through:
\[
Direct striking action
\]
Thus, free flaking is associated with:
\[
\boxed{\text{Direct Percussion Technique}}
\]
Step 2: Analyzing Block-on-Block Technique.
Block-on-block technique involves:
• Striking one stone block against another,
• Crude fracture production,
• Early core reduction.
It is not specifically identified as free flaking.
Therefore:
\[
\text{Option (A) is incorrect}
\]
Step 3: Analyzing Cylinder Hammer Technique.
Cylinder hammer technique uses:
• Specialized hammer forms,
• More controlled percussion.
It is not the standard term for free flaking.
Hence:
\[
\text{Option (C) is incorrect}
\]
Step 4: Analyzing Pressure Flaking Technique.
Pressure flaking involves:
\[
\text{Controlled removal of small flakes using pressure}
\]
This technique is highly refined and different from free striking methods.
Thus:
\[
\text{Option (D) is incorrect}
\]
Step 5: Final conclusion.
The technique known as free flaking technique is:
\[
\boxed{\text{Direct Percussion Technique}}
\]
Hence, the correct answer is:
\[
\boxed{\text{(B) Direct Percussion Technique}}
\]
