Hot on the heels of the Seismic™, knife designer Flavio Ikoma is at it again with a solid, no-nonsense everyday carry folding knife called the Linchpin™, built on utility without compromising on aesthetics.

The Linchpin‘s defining feature is the Deadbolt® lock. It’s simple to use and provides incredible strength. That means you can put the knife through the big jobs—digging into a pork loin or carving a wooden stake—and it won’t flinch. 

That doesn’t come at the expense of a smooth opening, though. The IKBS™ Ball Bearing Pivot System deploys the blade smooth and fast.

Plus, the durable, glass-reinforced nylon handle is lightweight with an excellent grip.

About the Deadbolt Lock

An exploded view showing the Deadbolt lock.

From a bird’s eye view, even an amateur can pick out true innovation from a sea of white-noise gimmicks. The dead giveaway: simplicity. In a world where “more” has somehow become synonymous with “better,” the true master uses subtlety to make his mark.

Flavio Ikoma creates at the intersection of simplicity and usability. When it comes to Deadbolt, you get that at a glance. But in hand is where it shines. Intuitive is an understatement, firing up and locking into place—one that’s proven to be outrageously strong—and a disengagement method that makes a slip joint look like it needs a manual.

About Flavio Ikoma

Some kids dream of being a ballplayer. Flavio Ikoma, of Presidente Prudente, Brazil, wanted to be a knifemaker.

In his adolescence, he worked on knives of the Japanese sword variety in his father’s shop. He has gone on to learn metallurgy, work with Ken Onion and become a force for innovation. Not only has Flavio brought to market the revolutionary IKBS™ ball bearing pivot system (with Rick Lala), but he also showed the world that there’s impressive strength in simplicity with his game-changing Deadbolt® innovation.
