CRKT Seismic Black

The CRKT Seismic Folder Knife is an everyday carry knife that features patented Veff Serrations on the drop point blade. The knife is has proven to be outrageously strong without compromising on simplicity or usability.

For years, Flavio Ikoma of Presidente Prudente, Brazil toiled over the mechanism that was to become the Deadbolt lock. Finally, it’s perfected: steel bolts interlock with the steel blade and the liners when it’s deployed to yield outrageous strength. The IKBS ball bearing pivot system ensures it opens quickly and smoothly. A prominent button sits at the pivot point on the highly ergonomic G10 handle for simple disengagement. Patented Veff Serrations offer superior cutting of cordage, rope, and fibrous materials.

As a finishing detail, Flavio added a discreet torx screw in the handle for deployment customization. Modify the blade detent for an easier or more powerful flip. The CRKT Seismic sets a new precedent for strength and simplicity.
