K415KXP description
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.

I PURCHASED THIS KNIFE TWO YEARS AGO AND IT HAS NOT LET ME DOWN YET. HOWEVER OVER TIME THE LOCKING MECHANISM WHEN THE BLADE OPENS IS WEEK. I HAVE TO PUT A LITTLE MORE EFFORT TO GET THE BLADE TO LOCK IN. VERY SMOOTH MOVEMENT BUT BEWARE. THE BLADE WILL NOT LOCK IN PROPERLY. CRKT Response: Hello, thank you for the review. Please know if your knife is not working properly that you can always send the knife in for warranty. We should be able to help you with this issue. Please check out the warranty page on our website for more information. Thank you!

CRKT Ken Onion hit a Home Run with this Ripple flip knife . I cannot believe it's priced this cheap $69 I would have paid more, I have a collection of over 100 knives Manufactured and Customs out of all of those this one by far is as good as my most expensive custom knife. There's so many points of perfection it has become my EDC for over 2 yrs haven't found a replacement yet? Yeah someone mentioned the screws coming loose but, it's no issue when my loosened I simply placed a dab of light lock tight on them never been an issue since and as far as the bearing goes yes occasionally I place a dab of gun lube on it just cause I love to keep it quiet and fast opening I adjusted the tension perfectly after 2 yrs. of flipping it open its still perfect ,Thank You Ken CRKT for this baby

The CRKT Ripple is a very versatile pocket knife. It is lightweight, the blade holds a pristine edge and the opening mechanism is very smooth. I like the feel of the handle and the overall size of the knife. All-in-all a winner.

Had this knife for almost 2 years now. Just sharpen it every now and then and it soldiers on. Great price for a great knife.

Received my Ken Onion designed folder about two weeks ago now. Some initial comments-- Knife is very lightweight for appearance and has an excellent tactile feel when holding it or retrieving from pocket. It took a few uses to get feel of the opening mechanism but it slings the blade out. I always dont do it with enough speed and it does not lock open but a wrist flick along with the finger stroke works great. The knife came extremely sharp right out of the box. The locking mechanism is solid and reliable. The build appears to be very good on entire knife. I do get a slight noise in hinge mechanism as if it needs some lubricant sometimes as I have habit of sitting around and repeatedly opening and closing blades on pocket knifes. Great knife especially for the price. Great blade.

This is the first CRKT blade I have ever bought hell this is the first blade I have ever spent $65.00 on.(I should have my head examined LOL) When I first saw this one I picked it up and fell in love with it. Very balanced , Best feeling folder I have ever held. Super sharp factory edge I could shave the hairs off my arm with it. I have had it for about 3-4 months My only Greif is the frame screws came loose and fell out. I lost all 4 out of mine and am waiting for CRKT to send me replacements. Also the super sharp factory edge does not last very long after quickly cutting about 4 fairly thin pieces of rubber it was still sharp but I could no longer shave with it. Other than that I have no complaints I just bought my second CRKT blade today the Ignitor with spring assist opening.
