The purpose of this study is to identify stone tool culture which was affected by climate change in the Paleolithic age by researching aspect of change of hammer stone.
This research looks at the chronological change of hammer stone through examination of the stone in sites, associated artifacts, tool kit, and transition of technique of making tools. The anticipated outcome of this study is as following.
First of all, hammer stones have time-periodic characteristic, and they seemed to have changed to be a shape of circles and their size was likely to be getting smaller.

Third, there is an observable change that the use of a hammer stone gradually decreased because of the introduction of pressure technique which is the arts of making blade and microlithic, and change of tools such as deer horn and bones.
Development of making stone tools in Paleolithic age in Honam province can’t be regarded as just an unilinear technique improvement but as an evolution by the environment and food resource for a long gap of time.
This research covers the change of hammer stone as a making tool and stone tool culture according to climate change in Paleolithic age in Honam province. Study on hammer stone have not been conducted a lot so far. But this research highlights various change of hammer stone by transition of the stone tool culture. We hope there will be more active research on stone making tools.
