"The cache of axes at Ferriters Cove, Co Kerry, indicates that complex ideas surrounding the use of axes may have pre-dated the formal beginning of the Neolithic".
The cache of axes might also be a cache left by a travelling salesman who knows better than to enter hostile territory with his whole stock. Several Bronze Age hoards have been identified as most likely being this kind of cache. I don't see why the same shouldn't be true for these axes (on limited info about the size of cache etc). Is the point backed up by any facts regarding the location, method of hiding etc? Or is it just stated for us to accept?
