The Microtech Ultratech Gen IV S/E Signature Outbreak Aluminum OTF automatic knife, Outbreak M390MK by Tony Marfione (11214-1OBDS) is a Double Action OTF automatic knife featuring a single-beveled Drop Point blade made of Böhler M390MK steel.

The side slide allows for automatic blade extension and retraction, while the Dual-Fuel Drive Train™ ensures consistent mechanism performance. The Crud Kutter™ system helps reduce debris buildup, 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, which offers high corrosion resistance, good edge retention, and properties suitable for a heavily used OTF automatic knife. The Flat grind supports effective and controlled cutting.

Drop Point, Single Edge, and Outbreak Finish

The Drop Point profile combines a strong tip with a rounded spine and a single smooth Plain Edge. The themed Outbreak finish covers the blade and handle, giving this Signature Series variant a distinctive, collectible look.

Outbreak Aluminum and Gen IV Mechanism

The handle is crafted from 6061-T6 aluminum and coated with a stylized Outbreak finish. Black hardware complements the themed design. The Dual-Fuel Drive Train™ supports automatic blade extension and retraction, the Crud Kutter™ helps direct debris away from the mechanism, and Torx screws and an integral glass breaker enhance the design’s functionality.

Technical Data

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 do you sharpen a Drop Point blade?

Sharpen the edge at a constant angle, guiding the tool along the curve of the blade. Near the tip, reduce pressure to avoid rounding the tip or altering the factory geometry.

How does the Double Action OTF mechanism work?

Pushing the slide forward automatically extends the blade, while pulling 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 debris buildup, but it is not a substitute for regular 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, it’s a good idea to check that the slide mechanism is working properly and ensure that the blade channel is free of debris.
