IMO to get a bend like that in a blade that thick you would need super strength and a 1/4" thick steel plate to ram the point into .
Also , if my eyes do not deceive me the left side of the blade is arrow straight right up to the first bend whereas the right side seems to taper in a little ; and what's up with the recurve ?
If a blade gets bent it's usually in one direction , not an S curve .
I still think it's intentional ; if not someone would have already tried to straighten it on an anvil .
