A functional replica for authentic details in drilling of stone, bone, and antler. More than any other replica, this particular device gets the most interest from the public in archaeology events and outreach programs. It allows one to pick it up and see history come to life, as it actually performs a task on the spot. In school programs, this piece also invites a discussion of engineering principles as well as archaeology history. The flint tip (real flint stone tip) is a modern knapped replica of Archaic Period flint drill tips (see Archaic period casts here), and is lashed in with plant fiber and hide glue. The picture below shows experiments drilling into wood, antler, and sandstone.
