In 2018, Jeff Park&mdashunder the tutelage of Ken Onion&mdashreleased his first production knife, the Crossbones everyday carry folder. It won Blade Show&rsquos coveted Knife of the Year award. Now, it&rsquos back and it&rsquos 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&rsquos right-hand shopman 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&rsquos making a second appearance.

Fully open, it measures in at a staggering 11&rdquo. The oversized blade contributes to 4.845" 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&rsquos finished with jimping on the backspacer for in-hand control and a Crossbones logo on the pivot.

The knife world couldn&rsquot get enough of the Crossbones, so we brought it back in a big way with the Jumbones.
