The Modular Knucklebone is Aroundsquare’s mix-and-match knuckle roller system, featuring assorted grip sections and end grips. For our September 2025 drop, we’ve paired titanium barrel ends with Delrin grips in six vibrant colors. While these differ from the original ergonomic design, the barrel ends provide a unique feel across the whole range of tricks and play styles–plus, you can stand them up on your desk so they won’t roll away. These modular knucklebones offer an approachable way to explore a fresh look and feel for your Kbones.
