Six Ripple models are available, in two sizes and two color schemes. The larger Ripple™ K405 models feature 3.125” blades, which are available in Razor-Sharp or combination serrated cutting edges. The smaller Ripple™ 2 models have 2.70” blades with Razor-Sharp cutting edges.
The modified drop point blades have a high hollow grind, swedged top edge, and a high satin finish. Steel is premium Acuto+ stainless, noted for its high chromium and molybdenum content and hardness of 59-60 HRC. They are 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 uncaged ball bearings on each side of the blade pivot in races which are machined into the stainless steel handle. 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 models are frame lock open build knives with stainless steel frames. The frame lock does not create an unsightly gap in the right frame, but its cut is neatly integrated into the grip design of the frame, which is CNC machined with a complex “ripple” textured pattern plus 44 small lightening holes.
