    (a kind of tool made of animal bone or horn)

The men in the Old Stone Age lived on fishes and animals caught by using chipped stone tools or Golgakki, and fruits and roots in caves.  

A chipped stone tool is also called Tajae Seokki and means the tool made by breaking a stone for easy use.  It was used throughout the  Old Stone Age and after this age.  It was frequently found in Korean relics of the Neolithic and Bronze Age.

Golgakki, a tool made of bone, was used as an important tool from the Old Stone Age with stone tools.  Since it was easier to handle bone and horn than stone and could make a sharp blade, the various tools were made of it and especially it was frequently used to make needles, arrowheads, hooks, etc.
