Marfione Ultratech ZBT Prototype 

Full Serrated - Zero Blade Play OTF (RARE)

The Marfione Ultratech ZBT Zero Blade Play OTF Prototype is a highly sought-after collector’s piece, featuring a full-serrated blade and cutting-edge ZBT (Zero Blade Play Tolerance) Technology for unmatched precision and stability. As one of only a few full-serrated prototypes ever made, this rare Marfione Custom Ultratech stands apart in both design and performance.

Microtech has been a leader in OTF knives since 1999, and this latest iteration sets a new industry standard. The Gen 3 Ultratech incorporates advanced patented features, a new larger actuator button for effortless deployment, and a user-serviceable system that allows for fine-tuning without compromising performance.

Crafted from 5” aircraft-grade aluminum, the chassis remains lightweight yet durable, while the 3.5” full-serrated blade ensures maximum cutting power. The sleek 0.91” width maintains its ergonomic profile, making it ideal for everyday carry and professional use. Enhanced with a uniball clip featuring a silicone carbide ball, this Ultratech is built for long-lasting performance.

Each prototype comes in a hand-signed box from Tony Marfione, adding to its exclusivity and collector’s appeal.
