Stoner,
Yes they call these French flints, but just wanted to say that back in our part of the UK,(N Yorkshire), we used to find a lot of flint this colour, that had been napped in Neolithic times.
As the big reserves of flint from further south were the good black flint, you Now have me wondering if the flint shards and tools we found were made from flint imported across the North sea?
Nice find, Mr J!
It looks rather used to me, (I think)
