The Microtech Ultratech Gen III EX-ZBP Interceptor Signature Black Aluminum, Stonewashed M390MK OTF automatic knife by Tony Marfione (1117EX-10S) is an advanced Double Action OTF automatic knife featuring an Interceptor blade made of Böhler M390MK steel, a milled 6061-T6 aluminum handle, and the Zero Blade Play system. The Signature Series design combines a double-beveled blade with a Sawback spine, a Stonewashed finish, and Generation III mechanical features.
A side slide controls the automatic extension and retraction of the blade, while the Dual-Fuel Drive Train™ ensures smooth and consistent operation of the mechanism. The Crud Kutter™ system helps reduce debris buildup, while the adjustable titanium clip with a roller allows for tip-down carry on either the right or left side of the Handle.
Böhler M390MK and flat grind
The blade is made of Böhler M390MK stainless steel, developed specifically for Microtech knives. The material offers high corrosion resistance, good edge retention, and properties suitable for a heavily used OTF automatic knife. The Flat grind promotes effective and controlled cutting.
Interceptor, Double Edge, and Stonewashed
The Interceptor profile combines a Double Edge blade with the distinctive Sawback spine. Two smooth Plain Edge cutting edges enhance the blade’s functionality, while the Stonewashed finish gives the surface a rugged look and helps minimize the appearance of fine scratches and scuffs.
EX-ZBP, Dual-Fuel Drive Train™, and Crud Kutter™
The handle is made of 6061-T6 aluminum and finished in Black, EX Machined. The Zero Blade Play system limits blade movement once extended, increasing the stability of the design. The Dual-Fuel Drive Train™ enables bidirectional operation, while the Crud Kutter™ helps direct debris away from critical mechanism components. Standard Torx screws facilitate proper maintenance, and the integrated glass breaker expands the knife’s emergency functionality.

Frequently Asked Questions
How do I care for Böhler M390MK steel?
After use, clean the blade and dry it thoroughly. Despite its high corrosion resistance, do not allow moisture, salt, or corrosive substances to remain on it. Before long-term storage, you can apply a thin layer of preservative.
How do you sharpen the double-edged Interceptor blade?
Sharpen each edge separately, maintaining a consistent angle and symmetry on both sides. Reduce pressure near the tip to avoid altering the factory geometry. Sawback components should not be sharpened like a standard cutting edge.
How does the Zero Blade Play system work?
The Zero Blade Play system limits blade movement once it is fully extended. This feature increases blade stability in the open position while maintaining the functionality of the Double Action OTF mechanism.
How do you clean a mechanism with the Crud Kutter™ system?
Crud Kutter™ helps reduce debris buildup, but it does not replace regular maintenance. Protect the knife from sand, lint, and excess oil. Use a small amount of a lubricant designed for OTF knives on the mechanism.
How do you care for the Stonewashed finish on the blade?
It is best to clean the blade with a soft cloth and mild detergent. Do not use polishing compounds or abrasive materials, as they may alter the distinctive appearance of the Stonewashed finish.
