Limited to 2 per household


We first launched into the live blade scene with the Krake Raken Tanto in the summer of 2019 to offer a competitive knife at an affordable price point.In 2020, we unveiled the Tsunami to push our manufacturing and design capabilities to the limit in search of peak performance. After two years of prototyping, we’re bringing the Hydro to the community as a premium live blade at a competitive price point.

The Hydro is our first sandwich titanium balisong, and it’s also the first to feature our unique double-angle chamfer design. Most conventional balisongs made by competitors only provide a single 45-degree chamfer which often yields subpar comfort. The Hydro’s double angle chamfer is two distinct chamfers, one at 30 degrees and the other at 60 degrees, which creates a much more comfortable, controllable experience. The Anodized Hydro offers an elevated aesthetic with beautiful colors including, Teal, Purple, and Green.  

The spacers are made from Ultem® (polyetherimide), which is naturally translucent amber. Rather than having the jimping milled into the handles, the Hydro’s jimping is built into the spacers which are raised slightly above the side profile of the handles. Looking to upgrade the handles to simulate a channel handle design? Consider checking out our Full-Length Spacers
