I know people will never stop calling bifaces "blades." But, really, a blade is a unifacial ribbon of chert/flint struck from a prepared core, with ridges running down the top side that are scars left from previous removals from the same direction or from the opposite end.
An artifact worked on both sides is a biface.
FWIW

That material looks like Rainey Buttes. Is it really heavy for its size? Gary
