Jumbones Blackout

Designed by Jeff Park in Mililani, Hawaii

When student becomes master.

In 2018, Jeff Park—under the tutelage of Ken Onion—released his first production knife, the Crossbones everyday carry folder. It won Blade Show’s coveted Knife of the Year award. Now, it’s back and it’s big. Really big. And this version is black as the night.

  • Larger Model: Jumbo version of the popular original Crossbones knife
  • Fast Opening: Flipper with IKBS™ ball bearing pivot deploys the blade fast
  • Strong and Lightweight: Aluminum handle combines strength with minimal weight
