I found another Copper Culture artifact last week in a farm field that was part of a late 1800’s homestead. The artifact is an Awl. Here is some information and example photo about it from the Milwaukee Public museum. The last two photos are of the one I found.
“Awls and needles constitute one of the most common artifact types found on Old Copper Complex sites. Similar to pikes, awls functioned as perforators, probably for puncturing hides. There is ample evidence to suggest that these tools were hafted onto a handle for easier and safer use. Currently there are about 250 awls ranging in size from2 to 40 cm in length in the MPM collection from Wisconsin.”
