The Benchmade 520SBK has a black colated 154-CM blade (partially serrated). The Presidio's anodized black aluminum handle features milled ribs that add gripability to the already contoured handle. The AXIS lock system makes the knife quick and easy to open and close. The pocket clip can be reversed for right or left handers. Overall this is an excellent knife with a good feel, something you could trust your life with.
