Using a Kadonger

This is Linda having just bashed Mark's fingers with a hammer. They are mending fences in Barnetts Wood Nature Reserve where every summer a few cattle are allowed to graze. Our job was to make the fences cattle proof.
 The item on the ground on the left is what we used to bash the fence posts into the ground. Not sure what its proper name is. , It makes a loud Kadonging sound as you use it so we called it a Kadonger.
