The illustration highlights the advancement of Stone Age cutting tools by contrasting one made 800,000 years ago with its predecessor dating back 1.4 million years.
It is clear that the earlier tool (tool A) looks very simple while the later one (tool B) is more complex and finely-produced. Major differences can be found in their shape, edges and tips.
Specifically, tool A is characterised by rough surfaces and edges. It is around 7 cm in length and has a small tip which looks sharp when viewed from the back but fairly blunt if viewed from the front. Overall, the tool has no particular shape and retains all characteristics of natural rocks, indicating basic tool making techniques of that time.
Tool B, however, showcases more advanced and elaborate manufacturing process. It is relatively larger in size and has skilfully sharpened tip and edges. Particularly, it was shaped like a pointed leaf with perfect symmetry and a round bottom to comfortably fit the user’s hand. These desired features are obviously the outcomes of delicate workmanship that had allowed prehistoric humans to get a better grip of gathering and woodworking.
