The Microtech Ultratech Gen IV Spartan Black Topographic Deep Engraved Aluminum OTF automatic knife, Apocalyptic M390MK by Tony Marfione (12234TP-10AP) is a Double Action OTF automatic knife featuring a double-edged Spartan blade made of Böhler M390MK steel and a black 6061-T6 aluminum handle. The deep Topographic engraving gives the body a distinctive texture, while the Apocalyptic finish emphasizes the blade’s utilitarian character.
A side slide controls the automatic deployment and retraction of the blade. The Generation IV mechanism utilizes the Dual-Fuel Drive Train™ and Crud Kutter™, and the adjustable titanium clip with a ceramic ball 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 provides high corrosion resistance, good edge retention, and properties suitable for a premium OTF knife. The Flat grind promotes effective and controlled cutting.
Spartan Double Edge and Apocalyptic
The Spartan profile features a centrally positioned tip and two smooth Plain Edge cutting edges. The double-edged geometry gives the blade a symmetrical, technical character, while the Apocalyptic finish helps minimize the visibility of minor signs of wear.
Topographic Deep Engraved and Gen IV Mechanism
The black handle is made of 6061-T6 aluminum and features a deep topographic pattern. The milled surface increases the number of contact points with the hand, enhancing grip and control. The Dual-Fuel Drive Train™ powers the drive system, the Crud Kutter™ helps reduce debris buildup, and standard Torx screws and an integrated glass breaker round out the Gen IV design.

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 leave moisture, salt, or corrosive substances on it. Before long-term storage, you can apply a thin layer of preservative.
How to sharpen a Spartan double-edged blade?
Sharpen each edge separately, maintaining a consistent angle and symmetry on both sides. Near the centrally positioned tip, reduce the pressure to avoid altering the factory geometry.
How does the Double Action OTF mechanism work?
Sliding the slide forward automatically extends the blade, while sliding it in the opposite direction retracts it. The Dual-Fuel Drive Train™ powers the mechanism in both directions.
How do you clean a knife with the Crud Kutter™ system?
Crud Kutter™ helps reduce the buildup of debris, but it does not eliminate the need for maintenance. Protect the knife from sand, fibers, and excess lubricant, and clean the blade channel regularly.
How do I safely store an OTF knife?
The knife should be stored with the blade fully retracted, out of reach of unauthorized persons. Before putting it away, check that the slide mechanism is working properly and that the blade channel is free of debris.
