The SOG Pentagon FX delivers professional-grade cutting performance with its premium CPM S35VN steel blade and tactical spear point design. This fixed blade knife combines advanced metallurgy with ergonomic handling for demanding field applications.
What Makes This Different
The Pentagon FX features cryo-treated CPM S35VN steel with black titanium nitride coating, providing superior edge retention compared to standard stainless steel blades. The spear point geometry offers exceptional penetration capability while maintaining structural integrity under stress. G10 handle construction delivers consistent grip performance in wet conditions where polymer handles may slip.
