Marty is gone so I can write now, and he can't argue with me
Hammerstones were only used for throwing at mammoths when you ran out of atlatls
O.K. Marty made a good point about the beginning and middle of the process being as important, if not more so, than the end. He also mentions his thoughts that the Western Clovis was fairly linear from start to finish, which I agree with. From what I know of pressure flaking, it would be very difficult to pressure flake a preform that is as flat as the Red Fenn point must have been before the final series of flakes. I think Mike mentioned about the extreme flatness of the Fenn point also. The only way I know of would be to do some FOG similar to the Egyptian Girzian knives to otain flat pressure flakes that cover the width of the Fenn Point. Now before we can make any statement concerning what technique was used, one must either try all currently know methods, or study the works of ones who are experimenting with new methods, before one can make any all encompassing statements about how they were or weren't made. And as Mike said if you can make one with all the right attributes, you probably have got something there in your technique
That is why I am so interested in seeing Swoose's technique and also doing some experimenting with a rocker punch technique, just to see what those methods are capable of.
From my own limited experimentation I would tend to agree with Mike that it was done with percussion but I haven't made one yet either
Below is a pic of an attempt at producing a thin, extremely flat biface using percussion, while retaining flake scars similar to the Fenn point. I know Marty will say I need to use some tough stuff like Bijou Hills, but this was the largest piece of material I had at the time (waiting for my KRF from Marty) plus the brittleness of obsidian is somewhat similar to the red phosphoria.
This was a spall I worked using only antler billet percussion and some limited hammerstones, the width is about 2 1/4inches and a little over 3 inches long. The piece is as flat and thin as the Fenn point, but I don't have the control I need over the sequencing and direction of the final series yet. Some of the flakes on the original are actually a collateral type if you look closely, and that's what I attempted on this. The rippling and some of the terminations, give me hope that I may be on the right track. Very tough trying to photograph obsidian and also show the flatness when in macro mode, which wants to give some perspective distortion (make flat round). No attempt was made to do any shaping, this was purely an experiment. The last pic shows the thickness of the biface.
