Instead of 7075 Aluminum, we use 43% glass filled Zy-Ex for the handles, and Japanese AUS 8A instead of American XHP for the blades. Our Zy-Ex Ti-Lites mimic the look of their more expensive counterparts almost exactly – but instead of 7075 Aluminum, we use 43% glass filled Zy-Ex for the handles, and Japanese AUS 8A instead of American XHP for the blades. The resulting knives are extraordinarily lightweight, while remaining remarkably strong, sharp and good looking - at a price almost everyone can afford!
