It was an issue of Knives Illustrated, found in a Hawaii drug store that inspired Ken Onion to enter the world of knife making. The former US Marine was taken under the tutelage of revered custom knifemaker Stan Fujisaka in 1989 and began producing his own blades two years later. Since then, Onion has produced knives for companies including Kershaw and CRKT and holds a binder’s fill of patents on various knife mechanisms and components.
Some of Onion’s inventions have become so widespread that they’re taken for granted. The most well-known of these is SpeedSafe, an assisted-opening mechanism that helps a folding knife blade spring out of its handle quickly but isn’t classified as a switchblade. One of Onion’s more recent innovations is Field Strip, a technology he created for CRKT with, with the flip of a lever and the spin of a wheel, brings a folding knife to pieces for easy cleaning. It’s creations like these that earned Onion a spot in the Blade Magazine Cutlery Hall of Fame in 2008; below, he shares the inspiration that’s fueled these creations.

Q: What got you started down the path of a knifemaker?
A: I had a thing for knives from a very young age. Growing up on a farm in West Virginia, we worked hard, and knives were an essential tool in our daily lives. That said, they were always more than a simple tool for me and I have fond memories of collecting pocket knives as a kid; cleaning them up, refinishing them and wondering what stories their various nicks, dents and scratches could tell.
I was stationed with the Marines in Hawaii, and when I got out of the service, I never left. I’d heard of a local knifemaker in the town where I lived and through friends was able to introduce myself. That was around 1989, and that local knife maker was the legendary Stan Fujisaka. He was incredibly generous with his time and knowledge and helped to teach me what he knew. I started crafting my own knives in 1991 and the rest, as they say, is history.
Q: How do you think about knife design? What’s your philosophy?
A: In a nutshell, I’d say that I try to make the craft of utilizing a knife, mankind’s second oldest tool, as simple and easy as possible. Materials, form, balance and ergonomics are all part of the equation, but essentially it’s ease of use and utility that we’re after.
