SOG Pent and Pentagon-Elite Folding Knife Series

The SOG Pentagon XR models are primarily built with CTS-XHP stainless steel, which offers superior edge retention and performance over common tool steels like D2. Certain premium versions, such as the Pentagon AUTO OTF, feature CPM S35VN steel for its exceptional balance of toughness and corrosion resistance.

The SOG Pentagon XR offers three distinct opening methods: a flipper tab, dual thumb studs, or by releasing the XR lock and flicking the blade open. This versatility allows the user to train for different deployment styles depending on their tactical or utility needs.

While the SOG Pentagon series features a dagger-inspired spear point blade, the folding versions are typically sharpened on only one side for safety and control. This design allows you to place your thumb on the spine for precision work, though some variants include a small sharpened section at the tip on the reverse side to increase piercing efficiency.

The SOG Pentagon series is highly effective for EDC because its blade geometry features a high grind that excels at slicing. The handle is designed with a neutral, symmetrical ergonomic profile that fits various hand sizes comfortably without the aggressive hot spots found on more specialized tactical tools.

Yes, the SOG Pentagon XR includes a reversible pocket clip that can be mounted on the left or right side of the handle for fully ambidextrous carry. The clip is a sturdy, fold-over design that provides a secure carry on a pocket or gear, though it is not a deep-carry style.
