I just got a pair of these for my son's use and they were very well made and inexpensive. I thought I would send out their information for those who are looking for competition nunchakus.

 

Dux Chux — Custom Xtreme Martial Arts Weapons

 

Home of MatchStyx ™ , BoStyx ™ and E-Styx™

 

MatchStyx™ are custom-crafted tournament-grade speed nunchakus designed to deliver the highest level of martial arts weapons performance in competitions. No other commercially available nunchakus match the

 

speed, responsiveness or eye-catching flash of MatchStyx ™.

 

Each 10” pair of hand-built MatchStyx ™ is created from ultra-durable

 

precision cut PVC. Slim and light, MatchStyx™ are both easier to grip

 

and offer a faster slash than standard-grade wood chucks. Each pair is

 

precisely matched, balanced and weighted, coming in at a lightning fast

 

3 ounces per pair. The specially developed internal weighting system

 

virtually eliminates grip rebound while providing the proper heft

 

required for competitive control.

 

MatchStyx™ are hand-tied to an ultra-fast 2 1/4” span with high-tensile

 

strength braided white nylon, tripled corded for strength and

 

flexibility. All exposed barrel edges are safety milled to eliminate

 

sharp ridges and wear points, greatly extending the life of the

 

hand-tied cords.

 

MatchStyx ™ awesome flash comes from a layer of holographic glitter

 

film permanently bonded to the core, which can then be covered and

 

sealed with a protective clear layer for practice durability and

 

improved handling. Available in a wide array of colors and finishes,

 

MatchStyx™ can be special-ordered with team colors or designs for

 

competition Demo and Xtreme Team use.

 

Specifications

 

10” barrel length, 2 1/4” cord, 1/2” diameter, approximately 22”

No weapon is indestructible. While MatchStyx™ are designed to be highly

 

durable in regular tournament competition, common sense should be

 

exercised and care should be taken in their use. These nunchakus are

 

intended for martial arts practice and forms competition only. They are

 

not designed for sparring, fighting, hitting stationary objects or

 

hitting other chucks, and serious user injury or damage to the

 

nunchakus themselves could result from using them in this manner. Match

 

Styx™ are intended for exhibition use only. Practice-grade MatchStyx™

 

can also be ordered with a polyfilm surface layer that will greatly

 

extend the life of the holo-film while protecting it from the wear and

 

tear of daily practice.

 

Nunchakus cannot be shipped to: AZ, CA, MA, Canada. Purchasers will be

 

required to sign a form indicating their agreement to use these

 

nunchakus solely in the performance of their martial art and not as an

 

offensive weapon.
