The Pulaski was an ancient tool for wildland fire fighters, basically a combination of an axe and an adze.
It was invented on Earth in the early 20th century, and was still in use with the Sphinx Forestry Service in the 16th Century PD. Except for the addition of a vibro blade edge to the axe part of the head, it was identical to the original design. (SK2)
