WebNevertheless, each of the two types had similar forms. Cores are simply pieces of chert or obsidian from which blades or flakes have been removed. Blades are very long, narrow, and likely removed from a core by pressure flaking. Flakes are chips of stone stuck from the core. Most obsidian tools begin as blades and most chert tools begin as flakes. WebFeb 12, 2024 · This paper targets developing new low-cost sustainable materials.
