I've had the opportunity to see the Havalon multi-tool, Havalon Hydra, and Havalon Titan in person. I honestly didn't like any real well. They all seemed like they would be awkward to use. I didn't actually use them on game so take that for what it's worth. The multi-tool would work for game, it just didn't feel real agile with the handle shape. I like a longer blade or at least one with more belly personally I've never been a huge Piranta fan for anything but caping anyway. The Hydra has such a long handle it just feels awkward and I bet it's not that much lighter than a Barracuda and Piranta anyway. The Titan is the best feeling of the bunch, but still not for me. I am not a huge fan of the regular blade's length or shape, and prefer a longer blade than the Piranta.
Again, all of them would work to do the job. None are the perfect solution for me. I'm kinda picky about my tools I guess.
