The Microtech Ultratech D/A OTF knife has been upgraded with a sleek and comfortable handle design for enhanced usability. This new version maintains the same dimensions, hardware, and durability as the "Tri-Grip" variation, but with added comfort for your hands and pockets. If you're not familiar with the Ultratech, it's a fully automatic knife with a double-action out-the-front mechanism. This means that the blade can be deployed and retracted using the thumb slide. The Microtech Ultratech is widely regarded as the benchmark for all OTF knives. Be sure to check out our Microtech Ultratech Review to discover why it's considered the King of OTF knives!
