Ultratech Gen III ZBP – Microtech’s Flagship OTF, Reinvented

The Ultratech Gen III ZBP represents the pinnacle of Microtech’s out-the-front automatic knife design. With over two decades of refinement, this latest iteration introduces cutting-edge features that enhance performance, durability, and user experience.

Note from Lone Star Knife & Supply

This Ultratech stands out with its Zero Blade Play (ZBP) technology, ensuring a rock-solid lockup with no movement when deployed. The Dual Fuel Drivetrain and Crud Kutter systems contribute to smoother operation and reduced maintenance.

Engineered for Excellence

At the heart of the Ultratech Gen III is a 3.55” tanto blade crafted from Bohler M390MK steel, known for its exceptional edge retention and corrosion resistance. The stonewashed finish adds a rugged aesthetic while minimizing glare. The dual-action automatic mechanism deploys and retracts with the newly engineered X-button thumb slide, designed for smoother, more effortless operation.

The handle is constructed from black anodized 6061-T6 aircraft-grade aluminum, delivering a balance of lightweight durability and a secure grip. Secured with upgraded Torx screws, the frame is built for long-term resilience in any environment. The ambidextrous titanium pocket clip, equipped with a ceramic ball, ensures a firm yet smooth attachment to gear or pockets, while the integrated lanyard hole provides additional carrying options. A redesigned, low-profile glass breaker offers emergency utility without adding unnecessary bulk.

Highly Recommended Dress Shirt

Honestly, I Love It. Fits Great, Neck Isn't Too Tight Like Most Shirts, And It's Comfortable. It Is 100% Cotton, So Dont Forget To Iron It Before Wearing It. High Quality Dress Shirt. Highly Recommended.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.

Comparable to high end mens shops!
Fit Type: Regular Fit, Color: Blue, Size: Large
Beautiful, heavy blue Oxford comparable to upper end mens store at 75% less! Full cut, great for casual wear or sending out for professional starching. Downside, no pocket, but I had mine monogramed wear the pocket would be and it looks like an expensive dress shirt. I bought more (with pockets) in blue & white
