Alessandra De Santis (aka Hydra Design), knife enthusiast as long as she can remember, has started collecting knives since she was 14 years old. Her passion for knives led her to become author of technical reviews on production knives since 2011; she is the author of numerous reports and articles published in a wide variety of trade magazines. Alessandra's knowledge about steels and materials comes from her university studies (she has a Master degree in Industrial chemistry of polymeric materials). She is also a firearms enthusiast and a Filipino Martial Arts practitioner. All these passions and experiences are reflected in her modern designs, always focused on efficiency and functionality.
