Hello guys, i bought this tomahawk from a local artisan and i swung it a couple of times and the axe head slipped off, i shoved it back in but i'd like to know if there is any way to secure it? I'd rather that it didnt slip off again (it doesnt have much of an edge at all so it isnt all that unsafe, and yes, i learned my lesson, i wont swing it at the air again).

EDIT:Thank you all for your advice, i'll definitely fix it up and keep it on my wall, untouched.
