The Benchmade 523 Presidio has a tanto-style 154-CM blade with a plain edge. The black aluminum handle features milled ribs that add grip ability in any direction to the already contoured handle. The AXIS lock system makes the knife easier to open and close and works equally well for right and left handers. The tip-down pocket clip makes carry easy and can be reversed for right or left handers as well. Overall this is an excellent knife with a good feel and weight, something you could trust your life with.
