My latest find - a Neolithic arrowhead

In the parts of Hampshire and West Sussex that I visit most often, I usually find Mesolithic flints - lots of them!  Rarely, I find Paleolithic implements.  Now, I've found a Neolithic arrow head to add to my finds (pictured below).

 It's probably an isolated later flint rather than evidence of settlement, but it's nice to know that the area where I live has been occupied on and off for tens of thousands of years.
