CRK415KXP: Ripple, Aluminum, Designed by Ken Onion
Columbia River Knife & Tool
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. 

Ken Onion - "Though I have been a devout knife collector since childhood, collecting mostly production knives and anything else I could find, I was unaware of the custom knife industry until 1989 when I saw an issue of Knives Illustrated at a local drug store. From there I found a local knife maker named Stan Fujisaka and begged him to teach me. I made my first knife in November 1991 and have continued the craft since.á While recovering from back surgery in 1996, I decided to try to design a folder that was easier to manipulate than what was available, and not a switchblade. The result was the first assisted opening knife I called "Speed Safe" (Knifecenter note: this model is not assisted) After finding some information on the whole patent process and consultation from an attorney, I got my first patent, creating a whole new category of knives between manual and auto."

This is my first flipper. I am a newcomer. I am really excited about it. What I have to say is that I am so happy with KC that I have already ordered 3 more flippers of the KERSHAW brand. Thanks for everything

Best knife I ever owned
This is actually my third Ripple (lost the first two due to fault with my fishing vest discovered after losing #2).It's easy to carry and open, holds a great edge, just heavy enough to know it's there, the ripple pattern makes a great nail file, and it's long enough to fit in my hand. I highly recommend it for fishing, opening boxes, and whittling.On a side note, the staff at knife center rock!

Nice Knife
I purchased this knife as a gift. It's solid and fits well in the hand, I love the handle. It's perfect for edc. Only drawback is that it is much smaller than I thought based on the photos, but this isn't much of a problem because it fits well in the pocket and is a lightweight, easy carry. Not for tactical or heavy duty use.
