1095

1095 is a popular high-carbon steel for knives; it is harder but more brittle than lower carbon steels. Many older pocket knives and kitchen knives were made of 1095. It is still popular with many bushcrafters and survivalists due to its toughness and ease of sharpening. With a good heat treat, the high carbon 1095 and O-1 tool steels can make excellent knives.
