Microtech Marfione Custom Dirac Delta D/E Blued Sharktooth Damascus AUMT509MCK

The Microtech Marfione Custom Dirac Delta D/E Blued Sharktooth Damascus stands at the top of the automatic knife world, blending elite craftsmanship, premium materials, and unmistakable design into a true collector-grade out-the-front automatic. Built under the Marfione Custom name, this Dirac Delta represents the pinnacle of Microtech’s precision engineering, delivering a knife that’s as functional as it is visually striking.

At the center of this piece is a stunning 3.79 inch double edge blade forged from Damascus steel and finished in a dramatic blue Sharktooth pattern. The layered Damascus construction produces a unique flowing pattern across the blade, while the blue Sharktooth finish adds depth, contrast, and an aggressive visual edge that sets this knife apart from ordinary production pieces. The dagger-style blade provides symmetrical cutting performance with razor sharp edges and a piercing tip designed for precision and power. It’s a blade built not just to perform, but to command attention.

Deployment is handled through Microtech’s signature out-the-front automatic system. A blue automatic thumb slide positioned on the face of the handle allows the blade to deploy and retract with a smooth, authoritative action. The placement of the slide enhances control and ergonomics, making the Dirac Delta comfortable to operate while maintaining the fast, reliable performance Microtech automatics are known for.

The handle is crafted from rugged black aluminum, precision machined to provide both durability and a secure grip. Its sleek profile balances strength with comfort, allowing the knife to sit naturally in the hand while maintaining a refined, tactical appearance. Blue hardware accents bring the entire design together, including the matching blue tip down pocket clip that ensures secure carry. Blue screws add a subtle custom touch that complements the blade’s striking finish, while the integrated glass breaker at the base of the handle provides added utility when it matters most.

Measuring 5.61 inches closed and 9.4 inches overall, the Dirac Delta offers a commanding presence while remaining lightweight at just 4.05 ounces. The balance between size, weight, and performance makes it equally suited for display, collection, or serious everyday carry.

As a true Marfione Custom piece, this knife arrives with a certificate of authenticity along with a black nylon zippered case and cleaning towel, ensuring the knife is properly stored and maintained. Every detail reflects the precision, artistry, and uncompromising standards that define Marfione Custom knives.
