Make a point of effortless looks. The Tanto Origin knife from our Founder’s Collection recalls the efficiency of COAST's earliest designs—with a sleek silhouette and all-metal construction for everyday durability and precision in the hand. The 3.5-inch, tanto-style blade, constructed of 9Cr18Mov steel with a glass-bead finish, flips open by the finger tab and is secured by a frame lock when in use—so that you’re safe no matter whether you’re opening a letter or cutting through a rope. The stainless steel pocket clip makes it easy to carry every day. Equally, this go-getting knife enhances your everyday wear at home on the avenue or out for an adventure. The Origin knife is backed by COAST’s lifetime warranty.
