Microtech Dirac Delta D/E OTF Knife Tan War Paint Aluminium, Tan War Paint M390MK by Tony Marfione (227-1TAWPS)

Microtech Dirac Delta D/E Tan War Paint Aluminum OTF Folding Knife, Tan War Paint M390MK by Tony Marfione (227-1TAWPS)

The Microtech Dirac Delta 227-1TAWPS is a full-size OTF knife from the Signature Series, distinguished by its decorative Tan War Paint finish covering both the aluminum handle and the M390MK blade. The Dirac Delta’s large design retains the characteristic front slide, and the double-edged blade emphasizes the model’s technical character.

The 96.27 mm blade features a Double Edge Dagger profile and a flat grind. The Double Action OTF mechanism allows the blade to be automatically extended and retracted, while the ambidextrous tip-down clip makes it easy to adjust the carrying position. Weighing 124.74 g, the model remains solid but not excessively heavy for its size.

M390MK – Steel for the Signature Series

M390MK was developed for Microtech in collaboration with Böhler and offers high resistance to wear and corrosion. In the large Double Edge blade, it helps maintain the sharpness of both edges for a long time while withstanding regular use well. The Tan War Paint version combines the steel’s functional properties with the decorative character of the Signature Series finish.

Double Edge Dagger and Tan War Paint

The Double Edge Dagger features a symmetrical geometry with two full cutting edges and a centrally positioned tip. The flat grind ensures predictable cutting performance, while the Tan War Paint motif gives the surface an irregular, military-style look and sets this version apart from standard Dirac Delta variants.

Tan War Paint Aluminum and Double-Action OTF

The aluminum body features a Tan War Paint finish that matches the blade. The handle design incorporates a rear section that serves as a backspacer, maintaining the visual continuity of the entire model. The front slide operates the Double-Action OTF mechanism, and the steel clip can be mounted on the right or left side in a tip-down configuration.

Technical Data

Frequently Asked Questions

What makes M390MK steel unique?

M390MK offers high resistance to wear and corrosion, making it well-suited for a large OTF with two cutting edges. With proper care, it retains its sharpness for a long time and does not require frequent full sharpening.

How do you sharpen a double-edged blade?

It’s best to use a guided sharpening system or diamond abrasives and work on each edge separately. Maintaining the same angles helps preserve the symmetry of the entire profile.

How does a Double-Action OTF work?

The front slide controls both the deployment and retraction of the blade. The mechanism performs both movements automatically, allowing for one-handed operation.

What does Tan War Paint mean?

Tan War Paint is a decorative finish with an irregular, tactical appearance that covers both the blade and the handle. It gives this version a unique look that sets it apart from standard color variants.

How do you maintain the Dirac Delta mechanism?

It’s important to protect the interior of the body from excessive dust and fine debris. If necessary, use a small amount of a light lubricant designed for OTF mechanisms, and avoid over-lubricating the interior.
