Microtech Ultratech EX-ZBP Bayonet Signature OTF Knife Natural Clear Aluminum, Apocalyptic M390MK by Tony Marfione (1120EX-10APNCS)

Microtech Ultratech EX-ZBP Bayonet Signature Natural Clear Aluminum, Apocalyptic M390MK by Tony Marfione (1120EX-10APNCS) – OTF automatic knife with Zero Blade Play™ system

The Microtech Ultratech EX-ZBP Bayonet Signature Natural Clear Aluminum, Apocalyptic M390MK by Tony Marfione (1120EX-10APNCS) is an advanced OTF automatic knife featuring the D/A system, part of the Signature Series. The EX-ZBP model expands on the Ultratech design with the Zero Blade Play™ solution, which is designed to reduce blade play after the blade is extended. Combined with the Dual-Fuel Drive Train™ mechanism and the Crud Kutter™ system, the result is an OTF automatic knife with smooth operation, fluid handling, and refined mechanics. The blade, made of Böhler M390MK steel, features a Bayonet profile, a flat grind, and an Apocalyptic finish, creating a design optimized for effective piercing, stable tip control, and high durability. The handle, made of 6061-T6 aluminum with a Natural Clear finish, a titanium clip with a rollerball, a Thumb Slide, and a glass breaker highlight the technical and collectible nature of this variant.

Böhler M390MK – Microtech powder steel for precision OTF

Böhler M390MK is a high-performance powder steel developed for Microtech in collaboration with Böhler, designed with an emphasis on wear and corrosion resistance as well as long-lasting sharpness. In the Ultratech EX-ZBP model, this material performs well when cutting tape, film, cardboard, cord, straps, and plastics, where stable edge performance and predictable blade guidance are essential. The Apocalyptic finish gives the blade a slightly weathered look and helps mask minor marks that arise during regular use.

Bayonet and flat grind – symmetry, piercing, and control

The Bayonet profile is distinguished by its symmetrical, slender geometry and a clearly defined tip, which facilitates precise blade guidance and effective point work. The flat grind facilitates smooth gliding of the blade through the material, maintaining a favorable balance between cutting sharpness and structural strength. The lack of serrations ensures the cutting edge remains versatile and easier to maintain. The tang grooves enhance the blade’s technical appearance, and the EX-ZBP format gives this Ultratech a more advanced character than classic OTF versions.

Zero Blade Play™, Dual-Fuel Drive Train™, and Crud Kutter™ – Mechanism with Zero Play

The most important feature of the EX-ZBP model is the Zero Blade Play™ system, developed to reduce blade play after deployment. The Dual-Fuel Drive Train™ mechanism improves smoothness and reduces the force required to activate the slide, while maintaining the fast, decisive action of the blade in the D/A OTF system. The Crud Kutter™ solution utilizes angled cuts beneath the slide that help reduce the buildup of debris that could interfere with the mechanism’s operation. As a result, the Ultratech EX-ZBP combines the speed of an OTF automatic with greater blade stability when open.

Natural Clear Aluminum and titanium clip with rollerball

The handle, made of 6061-T6 aluminum with a Natural Clear finish, is precision-machined to maintain the slim profile and technical aesthetic characteristic of modern Microtech designs. The bright finish of the body contrasts well with the Apocalyptic blade, emphasizing the collectible nature of the Signature Series version. The jimping on the spine and underside enhances grip control, while the titanium deep-carry right/left tip-down clip with a rollerball makes it easy to slide the knife into a pocket and reduces friction against the fabric. The handle features a glass breaker with a steel pyramid and a tungsten carbide ball.

Frequently Asked Questions

How does the Zero Blade Play™ system work?

Zero Blade Play™ is a blade locking system designed to reduce blade play after deployment. This allows the OTF knife to maintain greater rigidity during use and offers a more stable feel than classic automatic designs with greater blade movement.

What is the Dual-Fuel Drive Train™?

Dual-Fuel Drive Train™ is a drive system responsible for smoother blade extension and retraction in the OTF mechanism. This solution reduces the force required to activate the slide, while maintaining the fast and decisive operation of the automatic mechanism.

What is the Crud Kutter™ for?

Crud Kutter™ is a series of angled cuts beneath the opening slider that helps reduce the buildup of debris that could interfere with the mechanism’s operation. It’s a practical solution for users who carry a knife every day.

What makes the Bayonet profile stand out?

Bayonet is a slim profile with symmetrical, technical geometry, designed with an emphasis on precise tip control and effective point work. In this variant, the lack of serrations facilitates ongoing edge maintenance.

Does the Microtech Ultratech EX-ZBP have a glass breaker?

Yes, the handle features a glass breaker in the form of a steel pyramid with a tungsten carbide ball. This is a structural element of the knife that expands its functionality in emergency situations, but it is not listed as a separate accessory in the technical specifications.
