Here is an adze I cobbled together recently. The blade is a copy of an 18th century British Light Infantry tomahawk. The handle is a Wild plum (Prunus americana) branch that I had to trim from over a trail. I lashed the head on using a nylon cord, but rawhide would have worked better. For being an improvised tool I was impressed with how well it worked.
I was inspired by the journals of Lewis & Clark becase they mentioned that they made most of the tool handels they needed on thier journey to the Pacific from Choke cherry (Prunus virginiana) trees that grew along the Missouri River.
