Adding to cart… The item has been added

The Ultratech without question has been Microtech's flagship out the front auto knife since its induction in 1999. Recently it has gone through an additional aesthetic redesign after the overwhelming success and praise of the traditional styling. While the dimensions of the Ultratech remain unchanged, the handle has been stripped back down to its original roots--now offering a smooth contoured chassis, however still boasting the tri-angle hardware, a redesigned thumb slide and the glass breaker that now includes a press fitted ball bearing for a more comfortable, but still functional, user experience. Each Microtech OTF knife has extremely sophisticated internal mechanisms which improve the overall operational functionality and reliability. This model, the 121-13CC, features a contoured black handle complete with standard bronze hardware and an integrated glass breaker function along with a drop point blade in a bronze finish. Made in the USA.

    Bronze coating looks better in person. Excellent build quality. Requires more force to close the blade than to open. Wish glass breaker doesn't require special tool to remove for southpaws in order to reverse the pocket clip.
