Knucklebone - Delrin
AO2's Knucklebone is the original hardbody knuckle roller, make no mistake. 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

Delrin Knucklebone
Fantastic service and advice!
Fantastic product that is easy to use for an old beginner (is that last statement an oxymoron??)
Anyway, my only complaint is “I want to buy more items from Aroundsquare!!!

Awesome
Learned knuckle bones existed last year with my first ti slimini. I loved it and wanted to see how other materials would feel. Never touched a piece of delrin before until now. This knucklebone beat my expectations and then some it’s great in the hand and easy to control. 10/10

came for the begleri, stayed for everything else
i found around square as a begleri novice but after my first kbone i’m totally hooked. it’s such a different experience and is now always on me for when i can’t sling or have to be more conservative when out and about. i’ve now got 2 more kbones on the way!
