Cold Steel Spartan 21ST Folding Knife, 4.5" AUS-10A

The Cold Steel Spartan: A Modern Classic

Designed by celebrated custom knife maker Andrew Demko, the Spartan represents one of Cold Steel's most accomplished folding knife designs. This is a knife built for serious users who demand both performance and reliability.

Blade Design and Materials

The Spartan's blade is forged from Japanese AUS-10A stainless steel, a material chosen for its excellent edge retention and corrosion resistance. The stonewashed finish provides both aesthetic appeal and practical benefits—it hides wear and reduces glare. The blade geometry echoes the world-famous Kukri, delivering superior cutting performance across a wide range of tasks.

Handle and Ergonomics

The distinctive Kopis-inspired handle is precision injection molded from Griv-Ex, a durable composite material that provides excellent grip in wet or dry conditions. Heat-treated steel liners reinforce the handle structure and contribute to the knife's overall durability and balance.

Deployment and Safety

The patented Demko thumb plate offers versatility in deployment. Use it as a conventional thumb stud for traditional one-handed opening, or employ the proven "pocket draw" technique—snag the thumb plate on your pocket edge during the draw stroke for lightning-fast blade deployment. The famous Tri-Ad lock mechanism ensures the blade remains secure during use and safely locked when closed.
