AXE & CELTS
These four axes and celts illustrate different styles of manufacturing techniques. The hard stones, such as granite, are shaped by pecking the surface with a hammerstone (axe at left & third). More brittle stones, such as chert, are shaped by flaking with either a hard (stone) or soft (antler or wood) hammer (second from left & fourth). Then the surfaces are often smoothed to varying degrees.
