The Walker Blade Lock is a positive lock system that keeps the blade locked in the open and closed positions. The mechanism operates with a spring-loaded tab behind the thumb stud on the blade. To open or close the knife, depress the thumb stud while pushing forward or back to rotate the blade in place. With a sheepsfoot blade crafted from 14C28N steel and a stainless handle overlaid with durable G10, the Walker Blade Lock is one legend worth whispering about.
