Ultratech Gen IV – The Next Evolution in OTF Innovation

The Ultratech Gen IV represents a thoughtful step forward in Microtech’s iconic line of OTFs. Unlike previous generations, Gen IV ditches the Zero Blade Play (ZBP) system entirely—returning to a more traditional precision fit and finish while leaning on feedback from the Microtech community. 

This D/E version features a 3.5″ Bohler M390MK double-edge dagger blade in a stonewash finish, paired with a bold blue anodized aluminum handle. Deployment is fully automatic, and the design includes a glass breaker and pocket clip for daily versatility.


Note from Lone Star Knife & Supply

This is where Microtech has dialed back a few “bells and whistles” to focus on performance you feel. The action feels smooth, solid, and familiar—but updated. The blue handle with stonewash blade gives it visual pop while staying grounded in usable design.

Grille-ing Me Softly: A 30-Minute Makeover Adventure
Color: Single Slat Gloss Black, Size: 2019-2022 G20, Color: Single Slat Gloss Black, Size: 2019-2022 G20
Installing this grille was a breeze! It took me about 30 minutes, even with a minor hiccup of having to uninstall it to add the front camera panel I initially forgot. The grille feels incredibly durable, made from plastic that matches the quality of the OEM version. Plus, it gives my car a fresh, youthful look. Highly recommend for a quick and stylish upgrade!
