    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!

    Excellent product

    I purchased the Hydra false-live blade bowie in teal. Customer service was professional, helpful, and polite when I contacted them in confusion over receiving the bottle-opener trainer (the false-live blade ships separately, and I didn't understand that).
    I'm new to balisong flipping, but the performance of the bottle-opener trainer was so nice and smooth, and so easy to learn new tricks on (I can actually chaplain with this thing), that I bought another Hydra to put the false live blade on when it comes in, since I can't have the false live blade at my workplace and I can't imagine not being able to flip my Hydra at work.
    The balisong is light and responsive, and it really does "hug your finger" during chaplains. The handles have a very nice, grippy texture to them that makes maintaining control on many tricks much easier for a beginner like me. Aerials are also nice and predictable, and thus easy to do consistently.
    I highly recommend the bottle-opener Hydra for new flippers, especially if you can get it for the sale price of 80USD. I also really love my Nabalis Vulp, but the extra 20USD really goes a long way here.

    Also really cool that it comes with a case for 3 balisongs and extra hardware. I've been looking at cases, but I don't have a large enough collection yet to justify getting one for 40 or 50 USD that holds 8 balis. Really an excellent unboxing experience.
    (Ignore the umbreon sticker on the case. I was very excited about the case, because I had no idea it was coming lol)

    Wonderful product

    I love my Hydra. It looks and feels amazing to use. I’ve really enjoyed every Nabalis product that I own. I wish you guys had other gear as well. YouTube video placeholder

    It’s pretty cool, it didn’t come with the live blade though
