The following image show the process of making cutting tools from stone at that era.
Overall
, in both periods the tools have almost similar shape and size.
However
, more improvements are seen in tools B. On the one hand,
tool
A which is from 1.4 million years ago sows that cutting
tool
has triangle shape, has a bit rough surface with sharp ridges. It has 10 cm height, and a bulging front view,
while
the back seems flatter.
This
design and shape helps to be grabbed easily.
On the other hand
,
tool
B shows the progress of 0.8 million years ago which is quite similar the
tool
A. But with tiny differences
although
with
tool
B is
also
triangular with sharp cutting edge, but it has smoother surface than the
tool
A. Its height is about 8cm, and the weight is pretty thinner than the
tool
of earlier. The front and back views are
also
almost similar, only have the different surface smoothness.
