Carbon fiber liners reduce the weight of the Pentagon XR LTE by 35% compared to the standard Pentagon XR. A folding knife designed for defense, the easily carried SOG Pentagon XR features a 3.66 inches cryogenically heat-treated CTS XHP stainless steel, wide spear-point blade, and an ultra-grip G10 handle. SOG's XR lock enables smooth ambidextrous single-handed opening in three different ways, offering a solid blade lock once open, akin to a fixed-blade knife. It represents the next level of enhanced pocket knife capability, backed by Pentagon's proven pedigree.
