The Modular Knucklebone is Aroundsquare’s mix-and-match knuckle roller system, with assorted grip sections and end grips, players can build their own kbone setup based on their shape, size, and weight preferences. Use the drop down menu to select the components you want (click “purchase” then navigate back in your browser to continue shopping and add more to your cart").

At this time, we are offering three different grip sections, all sand-blasted (because it gives you the smoothest play), and all sporting the “a r o u n d s q u a r e” word mark (because legit, right). Details are as follows:
Titanium (regular length) in sandblasted or machine finished natty, and also in sandblasted with PVD coatings (shinobi/ black or sunset/ multicolour): 10.3g (reg $25)
Titanium “+5” grip (5mm longer than regular, sandblasted): 12g (reg $27.5)
Aluminum (regular length, all colours are sandblasted): 6.5g (reg $15)
• Aluminum “+5” grip (5mm longer than regular, sandblasted): 7.5g (reg $17.5)

As for end knobs, each has their own feel, and will resonate with the preferences of different players. Details as follows:
Original style titanium (machine finished): 33.0g per pair (reg $50 for natty or $55 for PVD coated)
Original style copper (machine finished): 63.5g per pair (reg $40)

The modular Knucklebones are designed to provide great play experience. The sandblasted grip sections provide smooth, low friction contact for smooth rolling between the fingers. The glossy end knobs provide good grip for manipulating the ends of the toy and preventing drops, and regardless of your metal choices, the contrasting finish creates an slick look that will develop nicely over time.

In general, the heavier ends relative to the middle grip provide a weight distribution which facilitates some aspects of play, while lighter ends make for a lighter assembly overall, which is preferable for some tricks and some players. While there is a lot of personal preference involved, the slimmer profile of the skinnybone style knobs may be harder for some players to work with, and may slip through the fingers and drop more easily than the wider standard knobs. Each model has its own pros and cons, as well as its own overall look and feel.

General Info on the Kbone

AO2's Knucklebone is the original hardbody knuckle roller. This is a simple skill toy that is manipulated with the fingers of one or both hands to perform tricks and patterns, or simply to pass the time. It is very discrete (unless dropped) and can be played in very restricted spaces, and in contexts where other showier skill toys may not be appropriate. There are tutorials already available online at the AO2 YouTube channel, and we’ll be publishing more in the coming weeks to help get folks started. 

The weight and hard material mean it will make a loud noise when it is dropped on hard surfaces, and has the potential to break things in its path. Be careful with it. Some metals are relatively soft, and will still show scratches and dings on the drop portions (see photo with original prototype for reference).. it falls with weight, so it hits concrete hard. 

Note from the designer: I developed the original knucklebone circa 1989 when I was a kid in school. The crude original version was made from some kind of polymer clay (see photo). The new version is better suited to bigger hands, and has been designed for smoother flow and better trick potential.  

Warnings: Metal versions are heavy and solid--can break things or hurt things if dropped. It is recommended that you play over carpet, couch, or the like, or outside. Delrin versions look almost tasty, so keep them away from young kids, and don't let anyone try to ingest them.
