打製石器
1. chipped stone tool; flaked stone tool
2. Lithic reductionLithic reduction involves the use of a hard hammer precursor, such as a hammerstone, a soft hammer fabricator, or a wood or antler punch to detach lithic flakes from a lump of tool stone called a lithic core (also known as the "objective piece"). As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process.
