Columbia River Knife & Tool and noted knife designer Ken Onion are proud to introduce their first collaboration together, the Ripple folding knife series. 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. This innovative and simple design places ball bearings on each side of the blade pivot in races which are machined into the stainless steel handle. It is compact and adjustable at the blade pivot screw if ever needed. Not only is opening and closing exceptionally smooth, the IKBS system is durable and requires little maintenance, and yields a folder with great rigidity and no blade play. The black titanium nitride coating on the handle is hand buffed to give a pocket worn look, lightly revealing the underlying stainless steel on the high points.
