Although after looking at yours again, it resembles more of a spokeshave/scrapper to me. I'm sure the well educated men and women on the site can help point you in the right direction. Good looking stuff though, happy hunting
Hey there you have a very nice hard stone Celt that is the big piece... A couple of projectile points and what looks like a knife blade.
The semicircular one is very interesting and I'm not quite sure what to call it at this point.
Crescent seems to fit
The half moon piece is called a Crescent. Nice finds
I have found a crescent before mine is small.
What is the size of the one you found?
Only one I have ever found.
