A POSSIBLE illustrates that it probably was made by "flake-over- grinding" with the use of some type of lever flaking "machine". One indication of this is the small areas
where the pressure flakes did
not remove all of the marks that were made from preforms that were ground smooth before they were pressure flaked. The other indication that this point was made recently is the jagged edges on some of the pressure flakes. This tearing effect is usually caused by excessive pressure that was possibly applied by some type of pressure flaking lever machine.
