The Kershaw Blackout Ken Onion Assisted Opening Combo Blade Knife KS1550ST is an iconic everyday carry folding knife designed by renowned knife maker Ken Onion. Known for its dependable performance, ergonomic design, and reliable SpeedSafe® assisted opening system, the Blackout has earned a reputation as one of Kershaw’s classic EDC folders. The KS1550ST combines a rugged partially serrated blade, lightweight construction, and practical functionality for work, outdoor use, and daily carry.
The 3.25-inch blade is crafted from Sandvik 13C26 stainless steel with a durable Tungsten DLC black coating. The blade features a combo edge design, combining a plain cutting section with serrations for increased versatility when cutting rope, fabric, packaging materials, and other tough materials. The DLC coating provides a low-reflection tactical appearance while improving surface durability and helping resist wear.
The black injection-molded Polyimide handle provides a lightweight yet strong platform with an ergonomic shape designed for comfortable everyday carry. The contoured handle offers a secure grip while maintaining a slim profile, making the Blackout easy to carry and practical for a wide range of cutting tasks.
