This Microtech Ultratech OTF knife, the 121-10AP, features a contoured black handle complete with standard hardware and an integrated glass breaker function along with a drop point style blade in an apocalyptic stonewash finish.

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. 

Made in the USA.

    Very sharp out of the box. Action is crisp. very sturdy and well built, it's a Microtech. The apocalyptic finish will hide hard use for sure. It is really different but I like it.
