Here
Doc has struck off the first large flake and is holding it in the
position it came from. You can see the edges as dark black lines.
After
studying the rock carefully, he has chosen this particular
corner because of the ridge you see running under his thumb. Flakes
tend to follow ridges quite well, and a skilled knapper can direct
which direction a flake will run.
Here
is the same flake removed from the rock. Note that it is a portion of
that same spall cone we looked at in the beginning when a BB hits plate
glass. Doc will simply remove more portions of similar cones at places
(and sizes) of his choosing, until he ends up with the desired results.
Here
Doc has removed the second flake, overlapping the first and along the
edge ridge he created with the first flake.All
