## Description

The Hammer Diesel has made its return. We took the same Diesel core shape that every Hammerhead loved and wrapped our trusted NBT Hybrid coverstock around it. The result is a great complement to the Rebel and Rebel Solid.
Updated with Hammer’s patent-pending carbon fiber outer core, this Diesel carries Hammer’s three-year warranty.
