Columbia River Knife & Tool® and noted knife designer Ken Onion are proud to introduce their first collaboration together, the Ripple™ K405 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. The modified drop point blade has a high hollow grind, swedged top edge, and a high satin finish. Steel is premium Acuto, stainless, noted for its high chromium and molybdenum content and hardness of 59-60 HRC. It is instantly opened by pressing the blade flipper with either hand. For safety while closed, the blade has a ball detent. Even the best conventional blade pivot bearings have some degree of friction which resists initial movement, or "stiction." In contrast, the Ripple blade opening action is almost friction-free due to the IKBS ball-bearing system. This innovative and simple design places eight uncaged 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 Ripple K405BX models are frame lock open build knives with stainless steel frames. In typical Ken Onion attention to detail, the frame lock does not create an unsightly gap in the right frame, but its cut is neatly integrated into the grip design of the frame, which is CNC machined with a complex"ripple" textured pattern plus 44 small lightening holes. The Ripple™ K405KXP and S receive a black titanium nitride coating, which we then hand buff to give a pocket worn look, that is to lightly reveal the underlying stainless steel on the high points. The Ripple™ K405KXP has a Razor-Sharp cutting edge, while the K405KXS features a combined Razor-Sharp and Triple-Point™ serrrated cutting edge. Both models feature a removable stainless steel mirror-polished pocket clip, high-mounted, and also with small CNC-drilled holes. This knife combines brilliant design, custom knife quality, and advanced manufacturing technology in true Ken Onion fashion.
Very disappointing. I first bought the "Wal-Mart version," the aluminum-handled linerlock, and fell quickly in love. Got this one, and was sorely disappointed. Its thinner, steel framelock handle has sharp edges that make it uncomfortable to grip firmly.
Go for the "cheaper" but hardly less capable, and definitely more comfortable, version.

A wonderfully designed knife. Light, and beautifully crafted. The assisted opening mechanism though, when pressed does not open the knife completely, and you have to jerk it in order for it to extend fully the blade. Ken Onion is trully a gifted artist.
CRKT Commment: The Ripple is not assisted opening. IKBS makes it feel that way but it is not.

I have quite a few knives. Many of them are CRKT. I just purchased the Ken Onion Ripple-3.125" Blade, Ti-nitride Charcoal Scales. I just got it today. It without a doubt has become my favorite knife. This knife is outstanding. It is by far has the best opening feature I have ever seen. It is light, it is thin and the blade is awsome. Wow, Ken Onion, you ROCK. Kershaws loss
