Historic glass and 'backed' knife

[Out Of Time]

Recently picked up two artifacts I think are interesting enough to share here.

A neatly made Backed-knife (is what I’m calling the obsidian piece). Mostly unifacial -though there is a little work on flip-side - with a specialized cleft of some sort. It’s spine (or ‘back’) is burin-cut creating a wide platform which allows the user to exert pressure for cutting or chopping. Found in a spot that has previously yielded Archaic material.

Also a small blade made from historic green glass. Fluted and micro-sharpened along one edge. I have special affection for worked glass partly because they are some of few artifacts I can date to within 50 years, but mostly because they represent the beginning of the end.
Thanks for looking,

Nice, I always enjoy finding tools like those

I agree. Tools are fascinating. Have to believe some forms were for very specific uses. This 'Backed' knife feels like one of those. Spurred scrapers too.

Those are very interesting.

Nice knife personal finds?

Hi southfork,
Absolutely. Freshly salvaged from Napa County vineyards.
You know my stuff from other site - which, for some reason (maybe registration issues since overhaul), I'm unable to post at these days....

Here's a neat one. Pretty rare in my neighborhood as it's struck from chert when obsidian is far more common. Older type too. Mendocino Concave.

Awesome stuff!
Yes, that worked glass is Contact Period, possibly 200 years old or more.
Good eye, nice find!

very nice, I like the color. nice edge work.

i have never hunted a vinyard, it looks like it could be interesting.

Those are both cool, gets you thinking how much glass is overlooked when looking for artifacts, personally I like contact period items a lot. I’ll have to remember to check the glass

When archaeologists dug at Ft Kaskaskia in IL along Mississippi River they found points made from European glass from early contact times. Marquette and Jolliet passed by there in 1673. The fort was built by the French in 1759.
