Introducing the CIVIVI Hypersonic, a Gustavo T. Cecchini design. This pocket knife has a unique design and is made to CIVIVI's sky-scraping standard of quality. It has smooth, fidget-friendly action via the flipper tab, locks up securely with the frame lock, and cuts like a charm with its razor-sharp Sandvik 14C28N steel blade. This steel type is beloved by knife makers and knife users alike for being easy to work with, extremely tough, and its ability to hold an edge. If you're looking for a neat update to your collection, we recommend giving this sweet flipper knife a try!
