- False Edge
Many knives have bevels not just along the bottom edge of the knife, but along the top as well. When present, bevels on the top edge are referred to as a "false edge". The false edge can be either sharpened or not. Whether or not the false edge is sharp, it serves to take metal away from the point, and thus enhance penetration. But taking away metal at the point also weakens the point, so this is a compromise between penetration ability and strength.
