The Benchmade Presidio 5000 has a 154-CM blade with a plain edge. The black anodized aluminum handle feature milled ribs that add gripability to the already contoured handle. The AXIS lock system makes the knife easier (and faster) to open and close. The 5000 series is automatic, pull the AXIS lock down and the blade opens automatically. The pocket clip can be reversed for right or left handers. Overall this is an excellent knife with a good feel and weight, something you could trust your life with.
