Tool Use By Humans
In Oceania and America, shark teeth were commonly used for tools, especially on weapons such as clubs and daggers, but also as blades to carve wood and as tools for food preparation. For example, various weapons edged with shark teeth were used by the Native Hawaiians (see example here), who called them leiomano. Some types were reserved for royalty. The Guaitaca (Weittaka) of coastal Brazil tipped their arrows with shark teeth. The remains of shark tooth-edged weapons, as well as chert replicas of shark teeth, have been found in the Cahokia mounds of the upper Mississippi River valley, more than 1,000 km (620 mi) from the ocean. It is reported that the rongorongo tablets of Easter Island were first shaped and then inscribed using a hafted shark tooth.

Famous quotes containing the words tool and/or humans:
“The veto is a President’s Constitutional right, given to him by the drafters of the Constitution because they wanted it as a check against irresponsible Congressional action. The veto forces Congress to take another look at legislation that has been passed. I think this is a responsible tool for a president of the United States, and I have sought to use it responsibly.”
—Gerald R. Ford (b. 1913)
“As humans have a prior right to existence over dogs by virtue of being more highly evolved and having a superior consciousness, so women have a prior right to existence over men. The elimination of any male is, therefore, a righteous and good act, an act highly beneficial to women as well as an act of mercy.”
—Valerie Solanas (b. 1940)
