It consists of a hard core made from FC61 steel, which is then encased in 100 layers of two differing types of special steel. Every blade features a one-of-a-kind Damascus pattern created in a highly-sophisticated process, making for a series of distinctive knives. Highly-polished Damascus steel knives with an etched ladder pattern, designed by Bob Kramer.
