The Ripple is the first collaboration between designer Ken Onion and CRKT. This knife is noteworthy for its exceptional manufacturing quality, premium stainless steel build, plus an almost unbelievable silky smooth and fast opening action thanks to the use of the IKBS internal knife ball-bearing system. The steel is premium Acuto, stainless, noted for its high chromium and molybdenum content and hardness of 59-60 HRC.
