They may have been your father's knives or your grandfather's knives — they may even be your knives. To help celebrate its 40th anniversary, BLADE released a three-part series recognizing the top 40 factory knives over that span (1973–2013). The first chapter pinpoints the top factory knives from 1973–1988. The second chapter includes 1989–2000, and the third chapter covers 2001–2012.
