The tanto blade made from Griv-Ex™- the latest in fiberglass reinforced plastic – Cold Steel's FGX Nightshade series knives are UV and heat stabilized to make them incredibly durable and impervious to the elements. The handles are made from deeply checkered Kray-Ex™ that’s molded directly onto the blade tangs in order to offer a slightly tacky-feeling textured surface that will give you a decisive and secure grip whatever the weather. The FGX Nightshade blades are unaffected by moisture. They never rust, warp, crack or split even in the most challenging environments. They are extremely lightweight, easy to be tied, tucked, or taped just about anywhere, and, since they are unaffected by all but the most extreme heat and cold, they are a natural choice for concealed storage both inside and outside of your house - from hedges and flowerpots to the refrigerator or the shower!
