The Benchmade 520BK Presidio has a black BK1 finished 154-CM blade with a flat grind and a plain cutting edge. The black anodized aluminum handle features milled ribs that add grip-ability to the already contoured handle. The AXIS lock system makes the knife easier and faster to open and close. The pocket clip can be reversed for right or left-handed use. This is a superb Mel Pardue designed knife that is built for years of hard work.
