The rounded lines are perfect for spinning and can be used to perform a surprising array of freestyle flows, technical tricks, isolations, and even aerials. There are a handful of tutorials already available online at the AO2 YouTube channel, with more to come.
The delrin version is light and smooth and is unlike metal and other plastics, delrin has a warm feeling, almost reminiscent of wood. It is also very durable, and stubbornly resists dings and breakage. It will scratch, but because it is relatively light, it tends not to take (or inflict) heavy damage when it is dropped. The weight and smoothness of the toy are variables that affect play, and each material seems to be suited to different kinds of tricks. The delrin version is conducive to quiet manipulation and two-play including transfers, twiddling between fingers, and two-handed rolls.
These are the standard size Knucklebone Delrins, which weight approximately 20g and are 6cm in length. each comes complete with cotton branded bag, colours of which may vary.
