The Native Americans used other Flint to Chip (Knap) away parts of the flint to fashion their hunting Arrows and their KNIVES Remember that the native Americans did not use METAL tools... When the flint is struck right it Flakes off and will leave very VERY sharp Edges.
So Anyway near Brownsville Ohio there was a super deposit of very GOOD quality Flint and the Native American's came from MILES AROUND to gather Flint and to Knap it and to Trade thingys fur the flint.
AND we got to go to the Flint Knappers Weekend.
These are some examples of the arrow heads that the knappers made...
It was a FUN day fur us... even if we WERE tired after walking like 87 miles.
