Hi Fernando

,
interesting axe heads ....these particular heads are called Palstave axes, the first one seems to have a 'hammer head' at one end.... on which I can find no info. These could be older than you think....many bronze age axe heads were never used but placed as 'grave goods' for the deceased ...to use in the after life
See this ....
