Microtech Stitch-A Out-the-Side Automatic Knife Tactical Black M390MK/Aluminum

The Microtech Stitch-A Out-the-Side Automatic Knife in Tactical Black M390MK with Aluminum handles delivers streamlined performance, rapid deployment, and uncompromising strength in a clean, all-black design. Purpose-built for demanding users, it combines advanced steel technology with rugged construction in a compact automatic platform.

The 3.75-inch spear point blade is crafted from Böhler M390MK premium steel, an exclusive alloy developed in collaboration with engineers at Böhler to enhance edge retention and corrosion resistance beyond the already proven M390 composition. Engineered for serious performance, this steel holds its edge under pressure and stands up to tough conditions. The black DLC (diamond-like carbon) coating further improves wear resistance while delivering a deep, non-reflective finish that reinforces the knife’s tactical character.

As an out-the-side automatic, the Stitch-A features a push-button system that opens and locks the blade with speed and confidence. The mechanism is designed for smooth operation and secure engagement, offering reliable functionality when fast access is essential.

The black aircraft-grade aluminum handles keep the knife lightweight without sacrificing strength. Their durable construction supports everyday carry and hard use alike, while the sleek tactical finish completes the cohesive design. A deep engraved stainless steel pocket clip provides ambidextrous carry options, and the stainless steel backspacer with integrated lanyard slot enhances structural integrity and utility. Measuring 4.75 inches closed and weighing 6.3 ounces, it offers a solid feel that remains practical for carry.

Proudly made in the USA, this Stitch-A reflects Microtech’s commitment to precision manufacturing, premium materials, and performance-focused engineering.
