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 thumb slide for more positive purchase and a rounded yet function glass breaker. The black color of the aluminum handle is a beautiful look against the bronze 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 when the knife is fired, it will operate effectively. The Ultratech's lightweight, one handed open and close action, slim shape and scalpel sharp, bronze DLC two-tone Hellhound tanto blade makes it a one-of-a-kind knife, only available through Microtech. This knife has proven time and again that it can withstand any obstacle.
