Product Description
Based on the custom "Headly" by world-renowned knife designer Dmitry Sinkevich, the Kershaw Tumbler is a strikingly handsome EDC that balances high-end aesthetics with hard-working performance. Sinkevich’s signature clean lines and ergonomic flow are evident in every curve of this folder, making it a "must-have" for collectors who demand custom-level design at an accessible price point.
The 3.25-inch drop point blade is crafted from high-performance D2 tool steel. This high-carbon, high-chromium steel is a favorite for its exceptional edge retention and increased corrosion resistance compared to other tool steels. The blade features a rugged stonewashed finish that masks wear and tear from daily tasks. The handle is a marvel of engineering, featuring G-10 with an integrated top layer of carbon fiber. Unlike simple veneers, this carbon fiber is a structural part of the material, which Kershaw then precision-machines to echo the textured look of the original custom Headly. To keep the knife lightweight (only 2.6 oz) without sacrificing strength, the Tumbler utilizes Kershaw’s patented Sub-Frame Lock.
