The Benchmade Presidio 523 is an excellent knife with a good feel and weight. The AXIS locking mechanism makes the Presidio easier and faster to open and close. The 6061 T-6 aluminum handle scales feature multi-directional ribs that offer added grip-ability to the contoured handle. The tip-down pocket clip makes carry easy and can be reversed for right or left handers as well. The 523S Presidio knife has a 154-CM stainless steel tanto blade with a non-reflective matte finish and a partially serrated edge.
