I was sitting in a camp (rendezvous) one time, working on a few points for my trade blanket. I was getting frustrated with myself because I`d broken more than I actually managed to finish into pretty, symetrical, thin "money points". I kept chasing that little bugger in the middle that messed with my defination of "done"... you know, that little hinge, those annoying hangnails, that little stack 1/2 way up the point...
A good friend sat there watching me getting more p/o`d with the results of my work. After a while he scooted a little closer to where I was sitting & asked if he could look at the ancient authentic points & blades that I had to show the flatlanders.
I told him that he was more than welcome to see anything I had. He asked me to show him the best of what I had in old stone... I pulled out a small unifacial ovoid knife/ scraper blade, & a couple other small points. He said to really look at the things I had in my hands... then look at the rest. His point was that there were more points & blades that had hinges, stacks, & other things that looked "wrong" to them. "Wrong" to us is a modern idea that wasn`t in their mindsets way back then. He told me that if I was making a point for a necklace or other finery, ya gotta make `em purty, cause purty sells... The most important thing back then came down to 3 major "gotta`s". Gotta have a decent point (to iniciate the cutting action), gotta have a sharp egde to continue the cutting, & still be thin enough at the basal end to be hafted in/onto whatever was to carry the point/blade in use wether it was an arrow shaft, atlatl foreshaft, or knife handle. Other than that, anything else was an option that didn`t affect the use of the tool. Hinges or stacks, away from the edge sucked, but didn`t affect the functionality. Overshot flakes that took out part of the other side of the just meant that he had to do a few pressure flakes to restore the sharpness lost (if even that).
As long as the point would put meat over the fire or an enemy to the "happy hunting grounds" it was a good point.
Sorry toi ramble on, but that`s just my $0.02 woth...
