This is the Hogue Elishewitz A01-Microswitch Automatic Folding Knife 24112 Drop Point Tumbled Matte Grey Knife. Hogue Automatics offer impressive speed and exceptional reliability. The A01-Microswitch is another addition to Hogue's quality line of automatic folding knives. It has a 1.95" tumbled stonewashed finish Wharncliffe blade and matte black aluminum handles. The Microswitch's unique patent-pending blade retention device allows for one-handed deployment and closure without placing the hand in the path of the blade. It comes with manual safety that locks the knife both open and closed to prevent misfiring.
Deployment is based around a strong, custom designed, oversized coil spring that has been extensively tested and integrated to provide force along the pivot's entire range of motion. The result is an automatic knife that kicks open with authority every time you call on it. Each knife is individually tested by Hogue and laser etched with a unique serial number before it bears the Hogue name.
