CRKT Jumbones Liner Lock Knife – Gray

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.

Just like its more compact counterpart, the Jumbones is modeled after the first custom release of designer Jeff Park from Mililani, Hawaii. Jeff has been Ken Onion’s right hand shop man for over ten years now, and, after much goading, finally released a custom design of his own. It was received so well by the industry, it’s making a second appearance.

Fully open, it measures in at a staggering 11”. The oversized blade contributes to 4.8” of the length, features a full flat grind, and is deployed swiftly and smoothly with an IKBS ball bearing pivot system. The brushed aluminum two-tone handle, when closed, resembles the shape of a dog bone and gives the Jumbones its name. It’s finished with jimping on the back spacer for in-hand control and a Crossbones logo on the pivot.
