Ken Onion Kershaw Knives
Ken Onion changed the knife industry. The Hawaiian custom knifemaker invented SpeedSafe assisted opening in 1998, creating the spring assisted knife mechanism that would define Kershaw's identity for the next three decades. His work earned induction into the Blade Magazine Cutlery Hall of Fame and multiple Knife of the Year awards. The partnership with Kershaw brought custom knife design philosophy to production-scale manufacturing—and accessible price points.
The Vegetable Series
Ken Onion's Kershaw designs share a signature naming convention: vegetables from the allium family. Each model scales the same sleek, organic blade geometry to different sizes and purposes.
The Kershaw Leek remains the flagship—a slim 3-inch blade in a 3-ounce package that disappears in dress pants or jeans. Two decades after its introduction, the Leek still defines what a gentleman's folder should be. Available in 14C28N, CPM MagnaCut, Damascus, and composite blade configurations.
The Kershaw Chive shrinks the Leek formula to a 1.9-inch blade, creating a legal-everywhere micro folder that weighs under 2 ounces. SpeedSafe deployment, frame lock, and tip-lock safety carry over from its larger sibling.
The Kershaw Scallion splits the difference with a 2.25-inch blade—more capability than the Chive, more discretion than the Leek. The same SpeedSafe spring assisted opening and slim frame lock construction in a mid-size package.
SpeedSafe: Ken Onion's Legacy
Every Ken Onion Kershaw knife features SpeedSafe assisted opening. The torsion bar mechanism holds the blade closed until you initiate deployment via thumb stud or flipper—then spring assist takes over, snapping the blade into position. This design keeps Ken Onion knives legal where switchblades are restricted while delivering fast, reliable one-handed deployment.
