Drive it into your workday and it'll bring BS to a screeching halt. Hot on the heels of the Seismic, Flavio Ikoma is at it again with a solid, no-nonsense everyday carry folding knife built on utility without compromising on aesthetics. The defining feature: the Deadbolt lock. Put it to the big jobs—dig into a pork loin or carve a wooden stake—and it won't flinch.
Flavio dreams up the big ideas in his shop in Presidente Prudente, Brazil. The Deadbolt is quite possibly the most impactful. Topping charts on both strength and usability, it's strong enough to withstand any daily job and so simple it's practically built with a user manual. The Linchpin shows it off with a 3.7" stainless steel modified sheepsfoot blade with a satin finish. The prominent flipper deploys the blade from between the ergonomic glass-reinforced nylon handle. The smooth, fast action is thanks to the IKBS ball-bearing pivot system.
Watch it laugh in the face of the toughest daily to-do.
How the Deadbolt Lock Works
Steel bolts interlock with the blade when it's deployed to yield incredible strength. A prominent button sits at the pivot point for simple, intuitive disengagement without fingers crossing the path of the blade.

Unbelievable value on sale
This is one of best knives for the money from CRKT on sale at KC, so glad I didn't wait. It's hard for me to part from hard-earned money, but am super impressed with the Linchpin flipper. The Ikoma design looks incredible but also feels good in the hand, locks up solid, zero play in any direction, safe, and easy to engage/disengage.The blade itself is 1.4116 stainless, best known for its use in Swiss army knives. It's not premium but using S35VN with this much steel would put this in the $150 and up price range. It's on the big and heavy side for EDC, but it can be done with the deep carry clip. The blade size and shape is versatile, allowing the Linchpin to serve as a tactical, utility, hunting or camp knife.

The Flavio Ikoma Linchpin Deadbolt is Simply Great
I now have Flavio Ikoma's Linchpin and Seismic Deadbolts along with Austin McGlaun's Clever Girl. These knives have me wanting more with Deadbolt. I like the deployment of the Deadbolt over any other design, including Automatic of which I have more than a few. These three knives are permanently in my EDC rotation. I didn't think I'd like the Linchpin as much as the Seismic, however, I find the Linchpin's grip to be a bit more ergonomic. The blade is excellent as well. I find the Linchpin to be more controllable for whittling which I enjoy doing. I have more than a few knives in my collection and the Deadbolt design has become my favorite mechanism for blade deployment. Thank you Flavio Ikoma and CRKT.
