I also believe it is a Colichemarde type but the blade is multiple bended exactly in the quite long transition area. So it is not 100% clear.
This might be a very interesting conclusion: the transition area is obviously the weakest point of a Colichemarde blade.
Another theory about the Colichemarde type from me is that it is lighter than later triangular blades with a nearly round base and maybe the ergonomics are slightly better.
