"The Black Titanium looks and feels beautiful. It carries the weight of titanium but with a unique finish that is perfectly matte. It glides through your hand straight out the bag." -Jake Wiens

The Knucklebone is a skill toy that is manipulated with the fingers to perform tricks and patterns.  It is very discrete and can be played in very restricted spaces. Use it any time or anywhere.  

The titanium model is the jack of all trades. It is heavy enough to provide the momentum needed to reliably perform momentum-based tricks, while still being light enough to manipulate smoothly between two hands without exhausting the fingers too much. The Black Cerakote is a ceramic based finish that can be applied to metals.

The Titanium 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. The titanium very durable but will still show scratches and dings on the drop portions.. it falls with weight, so it hits concrete hard.
