REDI blades are made of high quality AUS8 steel and were engineered for everyday use. They can be resharpened and can stand up to all the tough tasks a traditional fixed blade can. What sets the REDI apart is, after extended use the blade can be replaced rather than needing to buy a whole new knife.
