Few names carry as much weight in the modern knife world as Ken Onion, and nowhere is his influence more celebrated than in his long-running collaboration with Kershaw. As the designer behind some of the most recognizable and sought-after production knives ever made — including the iconic Kershaw Blur, the Kershaw Leek, and the Kershaw Scallion — Ken Onion helped define what an everyday carry folding knife could look and feel like. His signature aesthetic blends fluid, organic handle geometry with purposeful blade shapes and the SpeedSafe® assisted opening system he co-developed with Kershaw, creating knives that are as fast and functional as they are visually striking.
Ken Onion Kershaw knives span a wide range of sizes, blade steels, and handle materials, making the collection accessible whether you are picking up your first Kershaw Leek or adding a rare sprint run Kershaw Blur in S30V or CPM 154 to a growing collection. The ergonomics on every Ken Onion design are instantly recognizable — deeply contoured handles that fill the hand naturally, smooth weight distribution, and a refined fit and finish that has made these knives perennial best sellers for over two decades. If you carry a Kershaw, there is a good chance it has Ken Onion's DNA in it.
