When reducing large pieces into smaller pieces you will make "large flakes" of different sizes, some suitable to making hunting size arrow heads. When examining the flake it will have a smooth or flat bottom and then layers will rise from the flat. Sorta like ground level raising to the mountain tops. Sorta like going from Florida to the Blue Ridge Mountains. Somewhere in the side profile a center line will emerge as you progress both physically and mentally.
Now the question, should all the thinning flakes be taken from the "mountain top" or a platform set up and taken from the flat or bottom side as you reduce the perimeter and thin. Once you have started removing material from the flat bottom side then it will begin to appear as if you have two mountains rising from the center line you have created.
Should most or all the thinning flakes come off of the top mountain side or off the flat bottom side as it's reduced and shaped, or am I just missing the method entirely?
That was harder to ask than I thought it would be...
, hope someone will answer it
