Product Story

Hydra Bali is the first 7075 aluminum trainer of Nabalis, and it is inspired by the Hydra in Greek mythology.

Honestly, it's really difficult to produce the handles with 7075 aluminum, especially the anodized handles. We need to ensure the material is pure and its surface clean enough before anodizing.

You know, a small bias can cause huge color deviation. After tens of times of testing, we finally figured out the best producing process for the 7075 aluminum material.

Usually, aluminum handles would have bead blasted before anodizing. To get a metallic luster for the Hydra, we chose to make a mirror polishing and leave the handle soak in specific oil before anodizing it, finally getting it sparkling with natural metal sense.

Another innovation of the Hydra is the texture on the handle. Just like sketching, our designer draws lines with different intervals and tilt angles to make a specific visual effect, like a sinuous snake, meandering between two handles. When viewing from different angles, you can always get amazing patterns under the flowing light!

To some extent, the Hydra is a combination of state-of-the-art technology and the advanced design concept from Nabalis!
