The Provoke is the first knife ever to feature Kinematic technology, it stays neatly tucked away in transit and comes to life when there&';s trouble. Thumb pressure on the upper crossbar sets the chain reaction in motion, causing the blade to lunge to action while you&';ve got a firm grasp on the handle. Features a D2 steel blade with black titanium nitride coating for enhanced corrosion resistance and durable and lightweight hard anodized aluminum handles.
