Batten down the hatches.

We’re convinced that the word “dainty” isn’t in Designer Flavio Ikoma’s vocabulary. We take his new Deadbolt® innovation as definitive proof. With it, the Seismic™ everyday carry folder has proven to be outrageously strong without compromising on simplicity or usability—it’s got other folders quaking in their boots.
  • Innovative Deadbolt® locking mechanism is simple to use and provides incredible strength
  • Flipper opening combined with IKBS™ ball bearing pivot system deploys the blade smooth and fast
  • G10 handles provide exceptional grip in all weather conditions
  • How Deadbolt® Works

    Steel bolts interlock with the blade when it’s deployed to yield outrageous strength. A prominent button sits at the pivot point for simple, intuitive disengagement without fingers crossing the path of the blade.
