“Flint knapping is not sleeping on rocks,” instructor Mike Copithorne playfully told the group of about 40 children and adults who gathered at the museum to learn how to make arrowheads.

Other members who can’t find the time to scavenge their own tools use Knap Ins as a time to buy ... a recurve bow after learning to make his own arrowheads from the Michigan Flintknappers.

Knapping is what archaeologists call the process of removing flakes from the original pieces of stone (or cores) and then shaping the chosen pieces to make tools like scrapers and arrowheads.
