finally I finished this. The handle is made of purple leaf plum which had to dry before I wrapped the raw hide strip around.
nothing great but you can definitely break some nuts....I didn't´use it on the coconut but cut down some living bushes....it works.
Can imagine to use it for scraping raw hide or green wood as well.
One time I wanna make a bow with Stone Age tools, this is my first step - building tools.
