Microtech Dirac Delta D/E Black Tactical Standard

Overview

The Microtech Dirac Delta D/E Black Tactical Standard is the upsized evolution of Microtech’s innovative top-fire OTF. Built around the same ergonomic chassis and clever internal mechanism as the original Dirac, the Delta increases blade and handle length for users who want a more authoritative carry profile without sacrificing the platform’s signature top-button operation. The full black tactical finish keeps the entire package non-reflective and purpose-built.

Top-Mounted Firing Button

Unlike side-firing OTF knives, the Dirac Delta’s cover-mounted button enables a natural, intuitive thumb press for deployment and retraction. The geometry supports true ambidextrous operation without repositioning the hand on the chassis.

HALO-Inspired Ergonomics

The Dirac Delta inherits curved lines reminiscent of the legendary Microtech HALO, producing a distinctive in-hand feel that sets it apart from straight-sided OTF designs. The combination of size, contour, and top-button placement makes the Delta exceptionally fast to deploy from a natural carry orientation.

M390MK Dagger Blade & Integrated Glass Breaker

The 3.8″ M390MK double-edge dagger blade is built for piercing and utility, paired with an integrated glass breaker at the base of the chassis. The Black Tactical finish covers both blade and handle for a low-visibility, mission-ready look.
