AroundSquare Knucklebone - Titanium Black Cerakote

Prices are restricted to registered users

Quick overview

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 a handful of tutorials already available online at the AO2 YouTube channel, and we are adding more to the playlist on a steady schedule. 

The titanium version of the knucklebone is the jack of all trades. It is heavy enough to provide the momentum needed to reliably perform momentum-based tricks (think thumb rolls and sonics), while still being light enough to manipulate smoothly between two hands without exhausting the fingers too much. The titanium model has a sand-blasted finish that provides just the right amount of grip, while also helping to mitigate the stickiness that is sometimes felt when playing in humid climates or with damp hands. The titanium model is laser etched with the word "a r o u n d s q u a r e" around the equator. Over time, the sand blasted texture will tend to smooth out, giving way to a hand-polished finish which retains the same playability, but with a smoother and warmer feel. The natty version will tend to darken slightly as it gains a patina from contact with the skin. 

Although the titanium model is lighter than the stainless steel and brass, it will still 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. The titanium very durable but will still show scratches and dings on the drop portions (see photo 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.  

WARNING: 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.
