Features

Zippy's are the original balisong where the bearings rotate in two precision-milled raceways: a pivot system with unrivaled axial stability and smoothness.
Threadlocker-free double-nylock hardware tuning system keeps the Cycloid lockup tight without messing around with threadlocker.
Adjustable balance: Choose between nearly unlimited balance profiles by adding or removing Tungsten weights in both the blade and handles. The Cycloid balance profile can be adjusted to be blade biased, neutral, handle biased, and everything inbetween.
Unrivaled durability among plastic balisongs: made of the engineering thermoplastic Glass-reinforced Nylon PA12, the Cycloid HD offers serious rigidity and durability.
Hybrid channel/extension spacer handle design featuring tang pins for fantastic sound and the best durability of any plastic balisong.
Positive Jimping for extra grip on ladders and chokers.

The most durable and premium plastic balisong trainer available: The Zippy Cycloid is the best plastic balisong for beginners and experienced flippers alike, featuring the renowned Zippy bearing system, chanwich design, and adjustable balance.

Disclaimer

Please note that the texture of the Nylon handles is very distinct, and feels like 3000 grit sandpaper, and that some Cycloid HD's have cosmetic blackening on the sides of the interior tang pins (as shown in image 10).

The Cycloid HD is not compatible with Zippy Slim, Weight, or LED Caps.
