e/Chopper core

Information
has gloss	eng: In archaeology a chopper core is a suggested type of stone tool created by using a lithic core as a chopper following the removal of flakes from that core. They may be a very crude form of early handaxe although they are not bifacially-worked and there is debate as to whether chopper cores were ever used as tools or simply discarded after the desired flakes were removed.
