The Ultratech is Microtech’s original dual action out-the-front knife. With over 40,000 units in circulation since 1999, the Ultratech is regarded as a leader in the industry. 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 simplistic design, lightweight, one handed action, slim shape, and scalpel sharp blade make it an exclusive everyday carry knife. This version features a Double Edge Blade w/ Partial Serrations and Tan handles.
