Yes that is what I'm thinking.
I'm No expert knapper or anything but that is a flake with a little work on the side.
I don't really want to try to explain the whole process but platforms that are created by percussion flaking a biface are necessary in order to pressure flake anything more than just an edge.
There is no channel on that piece only a flat spot and I'm guessing the other side is completely flat.
There is a process to creating a well-made projectile point and that piece just does not fit into those steps.
A simple triangle may be able to be made from that... or a flake blade which looks like was already done
I call that a flake tool. I have some but they are smaller. Maybe these are fluted pieces I found last week IDK but they look like it. Broken, the 2 on the bottom.
Normally fluting takes place after the point or blade is completed. I have a friend that is a master flintknapper and has run flutes the full length of points. NOTE: that it doesn't always happen. If you care to view his work check out Mike Cook (Art of Ishi) on flintknappers.com.
