Like the rest of the Kershaw Starter series, the Filter has an automotive-related name and offers a machined look and smooth function. The all-steel design really shows off the BlackWash finish we put on both blade and handle. BlackWash gives the knife for a unique "well worn" look, yet the finish isn’t just for looks. It provides an extra measure of protection for the steel and helps hide any additional scratches you might put on your knife during normal use.
