In my opinion the two stemmed points you have there were used a blades and resharpened to the point of being exhausted and discarded.
The other three pieces look like broken tips

Most all of the large stemmed points were used as blades or perhaps spear tips.. I'm sure the large majority of them were used as blades since they show so much re sharpening.
Something like this would never fly correctly as a projectile.
