About Hydra Design
Alessandra De Santis
Italian freelance knife designer and founder of Hydra Design, specializing in tactical knives and EDC tools.
A knife enthusiast since her early years, she began collecting knives at the age of 14.
Her deep interest in the field led her to become a technical reviewer in 2011, publishing articles and in-depth reports on production knives across several Italian industry magazines.
Her expertise in blade steels and materials is grounded in a degree in Industrial Chemistry and a Master’s degree in Polymer Materials, providing a solid technical foundation for her design work.
In addition to her design activity, she practices Filipino Martial Arts (FMA) and holds formal qualifications related to the construction, repair, and sale of firearms, along with a collector’s license for knives and antique weapons.
After years of hands-on experience in testing and analyzing knives, she transitioned into knife design in 2018, starting with two limited edition fixed blades produced by Hydra Armaments.
Since 2019, she has been collaborating with international knife manufacturers, developing production-ready designs that combine functionality, ergonomics, and a distinctive visual identity.
