A/O Pocket knife on a Kershaw 1660 Ken Onion Designed Leek smooth edge blade. Fordite comes from many many years of spray booth painting in the old fashion where paint buildup occurred around the booth. This paint, too soft to work with for 40+ years, hardens over time and becomes what is now known as Fordite. Every knife is completely unique and equally valuable as there is only a very limited amount of Fordite.
