Pos my favorite flint find with great knapping , think about 3000- 2500 BC, if i remember from report. All my finds are recorded with the Royal Cornwall Museum
I cannot but imagine some industrious fellow, sat down, chipping away until he gets the shape that he needs. Arrow, knife, axe ... before tools were made by Spear and Jackson and were shipped by the lorryload. We do not know how lucky we area. Wonderful.
