Found this big obsidian spall.
This is a preform in the purest sense.
It's fresh off a core but somebody has started to work it at the tip.
Interesting to see that it's approximately knife shaped and this might be confirmed by close examination of the tip.
It looks like it was to be serrated on the top side and straight edged on the cutting side.
A couple of flakes have been removed three quarters of the way down on the right hand side.
I think this helps to read the intended shape.
Bulb of percussion sits at base.
Also seems to be abraded on the top side to create striking platforms - but I'd like a knapper to explain that part to me....
Hopefully this gives some insight on how these obsidian artifacts were made.
