The Hinderer Knives XM-18 3.5" Fatty Harpoon Tanto Blade with Sand 3D textured G10 is a precision-crafted hard-use tactical folder.  Nearly identical to the regularly produced XM-18, the Fatty version has a beefed up blade measuring in at 0.185" thick.  Overall handle thickness and weight has also increased slightly to provide a palm filling grip of this muscled up beast. Brand new directly from the Hinderer Ranch.

The Blade:  The 0.185" thick three and a half inch blade is stonewashed and can be opened via the integral flipper or dual thumb studs/blade stops. Rick's own 17-4PH state-of-the-art pivot system creates silky smooth operation; however, a bit of wrist action may be needed for flipping as Hinderers often have a light detent. The extended flipper features an "F" indicating this is a Fatty Edition XM-18.

The Handle:  Full titanium frame lock, liner, hardware and standoffs create one tough package while 3D texturing on the G-10 scale coupled with jimping all around create a solid grip. There is a bit of a choil to choke up on the blade for more detailed cutting tasks as well. This Hinderer XM-18 includes the famous Hinderer Lockbar Stabilizer and two-position titanium clip for tip up or down right hand carry.

About the Fatty: The Fatty Edition XM-18 fits regularly produced 3.5" handle scales, handle screws and pivot. Handle nuts are Fatty Specific.
