Phase 7SDM

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.
