The Ultratech will forever set the standard for all out-the-front knives. The Ultratech is Microtech's original dual action out-the-front knife and has been the foundation of their entire OTF line. Over the years, it has gone through several modifications, each time becoming more efficient and reliable. This version has the improved tri-grip texturing on the thumb slide for more positive purchase and a rounded yet function glass breaker. The blue color of the aluminum handle is a beautiful look against the silver color of the hardware and pocket clip. The Ultratech's spring remains in an "at rest" position at all times except when deployed. This ensures that the compressed spring will not become fatigued, assuring users that it will operate effectively when the knife is fired. The Ultratech's lightweight, one-handed open and close action, slim shape, and scalpel-sharp, Warhound Wharncliffe blade make it a one-of-a-kind knife, only available through Microtech. This knife has proven time and again that it can withstand any obstacle.
