CRKT and noted knife designer Ken Onion are proud to introduce the Aluminum Ripple™ K415KXP folding EDC knife.

The Ripple is noteworthy for its exceptional manufacturing quality, 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. Blade Steel is 8CR14Mov high carbon stainless steel with an HRC rating of 57-59. The blade 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 ball bearings built into the stainless pivot screw. 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 K415KXP model has locking liner. In typical Ken Onion attention to detail, the aluminum handles are CNC machined with over 40 lightening holes and small ripples. The handles are then hard anodized black and then the top of the ripples are polished off to create a pocket worn finish.

Ken Onion designed the stainless steel clip so it tucks away nicely in your pocket for every day carry and easy access.

This knife combines brilliant design, custom knife quality, and advanced manufacturing technology in true Ken Onion fashion.

Great knife. Does what it was designed to do.
Andrew H.
This knife is obviously not for heavy tactical work but definitely has a comfortable reverse grip. The action is great. The blade comes sharp out of the box. No blade play. Pivot is nicely lubricated. I'm guessing this was designed for everyday work, nothing heavy like whittling wood for tent stakes or tactical work (good in reverse grip though). This knife is really light and basically disappears in your pocket. The design is quite elegant in person.
Could be great but the clip is terrible
Chase B.
The ripple is a great knife in all aspects but 1. The pocket clip is awful. It is a major hot spot when using the knife because it flares up to a pointy tip. It looks goofy and it is tip down only.
