Phase 7SDM - Non-Catalog Starlingear Collaboration


The Blackside Customs x Starlingear collaborations bring together two icons of craftsmanship to create one-of-a-kind pieces of functional art. Known for precision-engineered blades and gear, Blackside Customs pairs its modern tactical design with the bold artistry and attitude of Starlingear. The result: limited-edition collaborations that are as collectible as they are uncompromising.

Precision Meets Artistry

Each collaboration combines the CNC-machined precision and performance-driven engineering of Blackside Customs with the handcrafted detail and rebellious spirit of Starlingear. Whether it’s a knife, pen, or gear accessory, every piece reflects the shared philosophy of building tools that blur the line between function and art.

Exclusive Designs & Limited Runs

No two collaborations are alike. From custom Starlingear faceplates and sculpted accents to unique finishes, textures, and hardware, these pieces stand apart from standard production models. Produced in limited runs, they’re highly sought after by collectors who value individuality and craftsmanship.

Built to Perform, Designed to Stand Out

While undeniably artistic, every Blackside x Starlingear collaboration maintains the strength, durability, and usability expected from Blackside gear. These are not just showpieces — they’re functional tools designed to perform, all while carrying the unmistakable edge of Starlingear’s design language.

Why Collect Blackside x Starlingear

Each collaboration is a rare opportunity to own a piece of modern functional art born from two masters of their crafts. Whether displayed as part of a collection or carried as a bold personal statement, these pieces embody exclusivity, craftsmanship, and attitude in equal measure.


The Blackside Customs Phase 7 SDM is a premium fixed-blade dagger that lives up to its name — Size Does Matter. Measuring 9.25″ overall with a 4.5″ double-edged blade, it combines reach, strength, and refined handling in one bold design.

Materials & Craftsmanship

Crafted from high-performance MagnaCut steel (with select builds available in 154CM), the Phase 7 SDM delivers exceptional edge retention and toughness. Each blade is finished in Cerakote, stonewash, or limited custom editions, making it as visually striking as it is functional. A milled fuller reduces weight while adding structural integrity and signature style.

Ergonomic Handle Design

The symmetrical G-10 handles provide a confident, ambidextrous grip. Custom milled hardware, jimping along the spine, and a lanyard hole add both utility and aesthetic refinement. With a blade thickness of 0.150″, the Phase 7 SDM is built to perform without unnecessary bulk.

Ready for Carry or Collection

Each dagger includes a precision-molded Kydex sheath with the Blackside logo for secure retention and quick deployment. Whether carried in the field, mounted to gear, or displayed as part of a curated knife collection, the Phase 7 SDM stands out as both a performer and a showpiece.
