Ken Onion

Kaneohe, HI

Ken is the real deal. The youngest ever inductee into the Blade Magazine Hall of Fame in 2008, he is recognized as one of the most innovative and successful knife designers of all time. In 1996 he created the first commercially successful assisted opening mechanism, which many knives continue to use today. Designer of the successful Eros™ folder series, as well as the award winning Hi-Jinx™, and new Homefront™ knife, Ken never seems to be at a loss for ideas.
