The new delrin Monkey Knuckles are the smoothest MK ever made. These guys give professional grade performance. They ship with soft 550 paracord, which handles like a dream. The knuckles and end grips are machined from high quality POM/ delrin material, which will hold up to any abuse you give them. They are slightly smaller than the wooden models, at just 35mm diameter, and weigh a bit more, at 75g per set. The result is a compact set that flows with excellent momentum. They come boxed and pre-strung, with two additional strings, a carry bag, an info card, and a couple of stickers.
Note that because these are so smooth on the string, they are slightly more difficult to learn on than the wooden models. Intermediate and advanced players will almost certainly appreciate and prefer the feel and performance of the delrin, but beginners may prefer to start on one of the wooden models, or to start developing their skills with just one ball on the string, until they develop a feel for the way these flow.
General Info on Monkey Knuckles
Monkey Knuckles is about as simple as a toy can be. It consists of two large balls tethered on a string, with two small beads at either end that serve as grips or counterweights. The design of the toy allows players to integrate elements of play from a number of other skill toys, including yo-yos, poi, and others, as well as totally unique styles of play. The idea is to use the different structural elements in order to create different patterns of motion, isolated tricks, and combinations.
Monkey Knuckles was first developed in 2003, partially in response to trends seen with other toys, including other skill toys, becoming increasingly high tech and complicated. Monkey Knuckles was an attempt to get back to a more basic kind of play that was not reliant on precision engineering, and would offer a rewarding experience for beginners learning their first tricks, as well as having the depth to allow advanced players to come up with more technical moves.
Monkey Knuckles allows for both individual tricks and continuous flow which links tricks together. One of the unique features of the toy is that there is rarely a drop or a "reset" required. When a trick is missed, it is relatively easy for players to recover by linking their play with a different move instead.
