Fixed blade knife by Boker Plus. The neck knife Featherweight, designed by Doug Hartsook, is made completely of carbon fiber. Although such a blade can never replace a steel blade, this knife, weighing less than one ounce, is a reliable tool for emergency situations and will not burden you with a heavy weight. It is not intended to be an everyday tool for frequent use or for executing fine cutting tasks. Includes a Kydex sheath and ball chain.
