Mexican/Spanish colonial spear points

[machinist]

This is deja vu all over again, my first thread here was about some "weapons" that turned out to be tools.
On one hand I am a little sad they are not spear points (except perhaps once in a while) but also thrilled to see the mystery solved.
Thank you all for your interest and work on this, I think Jim solved it and we can all feel good about an issue resolved.
