The Defiance knife is one of the coolest, most functional and reliable dual action automatic knives ever produced. The Defiance features a black coated 154-CM blade with ambidextrous thumb studs (you can use them to open the knife manually). The body is black anodized T-6 6061 aluminum, features a stainless liner lock mechanism, and has polished ivory micarta inserts on the front and back of the handle. The upper part of the front insert conceals a secret button to activate the knife automatically. The Defiance has a black finished pocket clip on the back (tip down) for easy carry.
