Possible Copper Pressure Flakers in the Archaic Era in Minnesota

<< < (2/8) > >>

turbo:
I've always known about the copper knapping tools found in the Great Lakes/Midwest region. I think the question (for me) is how widespread they were used but there's no doubt they were used. Here's a page from lithic guru Larry Kinsella on some Midwest copper pressure flakers to add to the discussion: http://flintknapper.com/NEW%20HACKER%20FLAKER.htm

Pardon if it's mentioned in the original article, I've just skimmed it.

Hummingbird Point:
Not doubting the use of copper, but I do wonder why no testing of the artifacts and/or flakes found in association with the probable pressure flakers was done to look for traces of copper.  Certainly some of the artifacts associated with the site must still exist in collections somewhere, so perhaps there is an opportunity there for modern science.  (I am assuming that if blood proteins can be identified on Clovis artifacts, there is some way to detect the presence of an elemental metal on younger artifacts, but that may not be the case.)

I have wondered that also. With the fantastic microscopes available today it would be a great study to view the edges of original points for what is trapped there.

John, I'm not questioning wether copper was used , My question is, If copper was used why are we excluding it from being ABO? I personally don't care  what people use to make there points, I like using all the tools. Antler, stone , copper even biscuits. I have tried ABO some and worked good on some materials and on others I struggled. I like  trying to knapp every material that I can get my hands on so I guess I will be a copperhead for now :D Bob

Thanks guys for the informative articles. This is turning out to be a really good discussion. I also am for testing artifacts for further evidence, but I don't know what permissions etc. might involved or whether the artifacts might have to be altered to do the testing.
