CRK401BXP: K401BXP Ripple 2 - Ken Onion Design
The Ripple™ folding pocket knife has become the anchor of the popular "gentleman's tactical" knife series from Ken Onion and CRKT.

These 2013 stainless steel handle versions ride low profile due to the considerate clip position and are designed to be used as an everyday carry pocket knife.

With their distinct look these knives will complement the refined taste of the distinguished gentleman. They slide in and out of a suit pocket easily and are also comfortable at home in your jeans in the garage.

Stylish curves and smooth flowing lines help to create the Ripple™ effect that defines the look of the handle. These distinctive frame locks feature an ambidextrous blade flipper for easy opening. The flipper style opener moves the blade with ease thanks to the smooth IKBS™ pivot system. The IKBS™ innovation is arguably the strongest, smoothest pivot system on the market.

The Ripple™ modified drop point blade with its high hollow grind affords the user a razor sharp edge with plenty of utility to cut across a wide variety of everyday tasks.

The Ripple™ - Stainless comes in 2.78 blade length (5.56 overall), Razor Sharp Cutting Edge version in both Gray and Bronze colors. There also is a larger blade size available in 3.16 (6.38 overall) with options of Razor-Sharp Cutting Edge or Veff™ Flat Top Serrations. All in Acuto 440 Steel 57-58 HRC.

Pros: Weight, Overall Quality, Blade Sharpness
Cons: None
Buy it While You Can
This is my favorite EDC folder. It is a shame CRKT discontinued this particular version of the Ripple. Pros: Thin, light and very handsome - a gentleman's knife without a premium price Blade shape and out-of-the-box sharpness A very nice flipper mechanism (no spring assist) Workmanship Cons: Right hand, tip down carry only Virtually impossible to find information on Acuto 440, although some compare it to 440C.

Great little bronzy
I use this blade for everything. It's great for a seco d EDC in pocket. The handle, blade and overall is a little beauty.ken onion makes some crazy looking blade designs, I love it. It's a bit small but great for 2nd pocket EDC. To close it it's a bit not in my delight, but do not regret buying this great Ken onion piece.
