Description
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."

Pros: Overall Quality
Cons: None
Jams with pocket lint
I use this as one of my EDC knives. I removed the clip and carry it fully inside my pocket. I like it, except that eventually it won't easily open and lock, or worse yet, won't close fully. When it looks closed, but the point of the blade is exposed by a millimeter or so, you're at risk for stabbing yourself when you reach for it in your pocket. The reason for its problems are pocket lint, which get into the mechanism and jam it up. So, if you plan on carrying this unclipped, and you don't mind taking it apart every month or two to de-lint it (don't lose those tiny ball bearings when you do!) it's a good knife. Otherwise, get something else, because this is the only knife I've ever had that's had this problem.

Pros: Blade Sharpness, Lock Type, Handle Material, Overall Quality, Pocket Clip, Ease of Opening, Handle Feel, Weight, Lock Ease of Use, Blade Material
Cons: None
Great all around carry knife!
I use the knife for day-to-day carry as the clip holds the knife secure in my pocket for immediate access. The knife is used for opening of mail, packages, cutting of binding on packages and if necessary immediately available for self defense. A great Ken Onion design for numerous uses and immediate opening on demand.
