Splitting large tree trunks is not difficult to do.
The job is done using wedges made from beech (a wood that is quite shock-resistant) and hand axes with antler head. These types of tools are common in archaeological layers that are contemporary with the creation of villages, where they were abandoned along with woodchips and woodworking waste.
